RIGOL DS1102Z-E

[gret151]

Hey, I'm new here but just wanted to check if anyone else has encountered these RIGOL (maybe) scopes that have the product number DS1102Z-E

They're implied to be part of the 1000-Z series like the popular DS1054Z. I only saw them today and were all in either sites like aliexpress or banggood. I did find a (supposedly) Chinese RIGOL site where the product is featured and also found a Chinese shopping site where the Oscilloscope is sold and even has reviews.

It's supposedly a 100MHz, 2-channel scope, a sort-of successor to the DS1102E.

Obviously, I went into this more than a little skeptical but I wanted to ask if any of you that have more experience with these can verify if these are a real RIGOL product that is specific to China or is a very elaborate way of fake oscilloscopes. The site looks quite real but I could be wrong. There are legitimate RIGOL products there too. If this is real, it's quite competitively priced (even cheaper than the DS1054Z).

The Chinese Rigol Site (?): https://www.rigol.com/news/news/48.html

I'd guess it's an unhacked version of this:

[MackWill]

I have received one of these scopes today, first impression heavy enough to not move when pushing buttons. Not a suitable person to offer an insightful review. But here are a few pictures of the unit at a cost of ~240 USD

Hi,

Do you know for sure if it can be hacked to the DS1202? The DS1102 comes with all options and licences unlocked.
Do you maybe have the firmware for the DS1202 ?

I would be very thankful for any information, have a nice day.

It doesn't look like it's available outside China yet.

It's 99.9% likely to be hackable but I can't tell you if it's as simple as using Riglol.

Note: If you're not using BNC cables and direct connection to the 'scope then the extra 100Mhz won't be very helpful anyway, it will mostly expose the limitations of non-active oscilloscope probes. Maybe better to use the 100Mhz low-pass filter.

(in exactly the same way that using 1x probes without the 20Mhz low-pass filter is foolish).

Bottom line: For 260 Euros? Get one anyway!

[maseryoda394]

 Thank you for your reply .

I already got it, it comes also with all the options unlocked and 150 MHz probes, and I only paid 215 € not even 250.I just wondered if it's hackable. to be fair 100MHz is more than enough for my current application of measuring DC TO DC converter ripple and eliminating it using the capacitance multiplier as shown in Dave's video.

Thanks again.

[maseryoda394]

It is not available from outside China officially from Rigol.
But many sellers on aliexpress do offer it.

[Fungus]

Wow. That has to make this the new "entry level oscilloscope recommendation" when people ask here.

[Fungus]

Not that options are easy to remove as well. It should work with Riglol if you can find/guess the right letter code for "200Mhz".

[Microdoser]

Got one of these turning up today. Looks a good scope for the price, especially with all the features unlocked.

Does it have an encoder problem like 1054z had? Seller said that this problem was solved. Can you select menu options without any problem? If problem still exists what kind of encoder it has? The same type as ds1054z? Half handle type?

I don't know about the encoder problem that the 1054z had so I can't say whether it is still present. Menu options can be selected easily, although the selection knob is a little sensitive.

Not sure what 'half handle type' means.

I don't recall any problems with the encoders. Menus have always worked perfectly.

(as well as menus can work with a twisty push knob... but that's another story and doesn't just apply to Rigols).

When I use this scope, I replaced the encoder with a walking one with a tactile sense of turning-steps. It became much more convenient. Encoded bought on Aliexpress, but it's not the SMD had to bend the legs.

Sure, but that's not just a Rigol problem. People do that to lots of 'scopes.

Another trick is to replace the knob with a bigger one, it gives better control and doesn't break the "warranty void" sticker.

The GW-Instek 'scopes have a separate button to avoid menu mis-selections.

I just bought a 'scope that doesn't do everything through a stupid twisty knob and it's awesome.

I also have a different scope now. With a touch screen, this solves the problem - an awkward encoder is almost unnecessary.
Sometimes I connect a wireless mouse.

I'm definitely not going back. People moan about the vertical position response on Rigols (although I never once felt it prevented me from doing my work) but even if they fix that you'll still be using a horrible twisty knob to navigate the menus.

I expect that touch screens will be standard within a couple of years, even in low-end 'scopes.

[Dlrowdna]

I have ordered this one: https://m.aliexpress.com/item/10000056483250.html?spm=a2g0n.orderlist-amp.item.10000056483250&aff_trace_key=c6d3c64b86684866a1233c319847e33b-1604244217899-04313-mr6wR6CC&aff_platform=msite&m_page_id=4051amp-JqCa6HqVGmo1_LoyvHcC5A1604684008339&browser_id=bc08df6557be403a99978184b819c59d&is_c=N
I've got my parcel. This oscilloscope lags. My old friend dso5102p much better in behavior. Not impressed with my purchase.

Hi there,

does anyone have a new experiences with DS1102Z-E?
Maybe to unlock 200mhz band?

I have the same question. Is it worth to buy DS1202Z-E as well?

[Microdoser]

Hi there,

does anyone have a new experiences with DS1102Z-E?

From what I can see it is a scope already unlocked to 100Mhz.

It is not possible to turn it into a 200Mhz scope.

There's a matching 1202X-E model so no reason why the 1102X-E shouldn't be unlockable.

So there is. Has that been released recently, like the last three months?

When I got mine I did a check and I did not find a 200Mhz version. Now I wonder whether I missed it or was released in the meantime.

EDIT: Nope, looks like it has been around for a year

Does it mean 1102Z-E can be unlocked to 200MHZ? I unlocked by using a key provided on this site http://gotroot.ca/rigol/riglol/ and unfortunate bandwidth still is at 100MHz

[Fungus]

Probably, but nobody here knows the code to use yet.

There's no "200MHz" option on there. 

There's probably a combination of letters that will do it. Somebody needs to download the source code for Riglol and play with it, figure out what they are.

[Dlrowdna]

I hope no one ordered the encoder from my link? It doesn't work. It jumps over one menu option. I discovrred this only after it came to me. Sorry.
Looking for a suitable type.

If that is possible, it should be very easy to find out. One just have to play with the bits (using the letter combination is harder to find it).

Does this scope have any licensable option?

It's unlocked by default. What do you mean by saying licensable? Any tutorial on how to check bits in the firmware? Thanks!

I am not sure if I am doing correctly but this is what I tried but unsuccessful. Enter keys and it said Options successfully installed but Bandwidth is still 100M

[Microdoser]

I remember having a go when I first got mine, the only thing I could find to activate that wasn't already unlocked was the 500uV range which I was advised was 'buggy' so I reverted back to vanilla.

Still, interested to see if anything comes from this. I'm rooting for you.

[caheo]

You're doing ok. No need to specify the privkey.

Show us a printscreen of the option screen after that DSF9.

I also attached version screenshot as well. Thanks!

What's "DG" 

[Fungus]

I think it was activated by the DSF9, right? Digital Generator...

Yes, it appeared after DSF9 but I don't know what it is.

Now, try DSJR.

I find it very hard to believe. The only way to be sure would be to open up one of each and look at the components.

Is there a chance which I need to change my device to DS1202Z-E model to make it work???

[Microdoser]

After doing my own attempts I became certain it was not possible to get 200Mhz out of a 1102Z-E. I have watched with interest and hope but I still remain certain that it is not possible with this scope.

If anyone does a teardown of both or knows where teardowns of both might be, I would be very interested in seeing them but I suspect there will be vital differences.

[Fungus]

Another way to test this would be for a 200MHz model owner to try to downgrade theirs.

Hi,

just got my 1102Z-E.

What I mentioned is that there are LEDs under the plastic below the CH1 CH2 buttons, they light up shortly during boot.

I wonder: Is the DG (Function gen?) usable when set free?

And what is the Power Analysator?

Oh Edit/BTW: Is there a newer Firmware version than my 00.06.02?

BTW2: I find the Multipurpose Knob very sensitive... Often changing the selection during enter/press

Hi,

just got my 1102Z-E.

What I mentioned is that there are LEDs under the plastic below the CH1 CH2 buttons, they light up shortly during boot.

I also see those four LED lights on boot. These match the position of four buttons on a DS1104Z which suggests they share common circuitry behind the front panel.

This raises the question:

Can a DS1104Z be hacked to 200MHz?

[calli]

I still wonder if I can use a code to have a function gen? Or ist the 1102 just lacking the HW?

And whats the Power Analyser OPtion?

Best,
Carsten

[Fungus]

Function gen needs more chips on the PCB.

[Fungus]

Yep. The PSB with the buttons will be common to all models.

Can a DS1104Z be hacked to 200MHz?

No.

(and you wouldn't want a 4-channel, 200Mhz 'scope with only 1GS/sec, it breaks Fourier theory).

(and you wouldn't want a 4-channel, 200Mhz 'scope with only 1GS/sec, it breaks Fourier theory).

Then IMO a sharing of some internals lends credence to the idea that the DS1102Z-E can't be hacked to 200MHz. It seems more likely the DS1102Z-E is a stripped down version of the DS1104Z than a stripped down version of a 200MHz capable scope.

[tv84]

But, then what is a DS1202Z-E ?

[Fungus]

But, then what is a DS1202Z-E ?

You can do 200Mhz when you only have two channels - 1Gsample/sec divided by two doesn't break Fourier.

[Microdoser]

But, then what is a DS1202Z-E ?

Fair point. So the thing to check, for pointers on unlocking a DS1102Z-E, is how to limit a DS1202Z-E to 100MHz and then unlock that back to 200MHz.

[nightfire]

As I noted the DS1102Z-e being available on german amazon, I wondered if anyone could share some experience in daily handling.

My use would be a beginner to a DSO to get additional coverage of routine measurements, like jitter on some USB Power supplies etc. - and on my bucket list for the future I still have the item: Measurement of the burning time of a photographic flash by converting the light with a photodiode and measure that with an oscilloscope...
(Flash duration is about between 1/10000 sec and 1/100 sec for slower studio flashheads, meaning some duration betwwen 10 ms and 0,1ms)

For the price of about 260 € for Prime members including shipping, I cannot complain, and if I really would feel the need for a better scope, I would know what I have to buy and won't have much loss of value by selling it after a short time...

Opinions?

Timing of pulses can be done to about 4 nanosecond resolution. It will definitely be able to do those things.

same question for me.
Scope is on Rigol-Shop EU, but only with payment creditcard.
https://shop.rigol.eu/product-digital-oscilloscope-ds1102z-e

I would like to buy one, but with paypal or Klarna.

Would like to know, where to buy, maybe in Europe.
Thanks.

I got mine this week from Amazon Germany- as Prime Customer the price difference is not much different considering Rigol EU charges some additional €€€ for shipping.

[calli]

Great, I planned that some time but was too lazy until now!

C!

[Piton]

I want to ask everyone if this is the case: when the second channel is turned on, the first, together with the second, shifts to the minimum vertical limits, but if you switch both channels to the ground, and then back, then everything falls into place. It is not yet clear why the relay always clicks when the second channel is turned on? There is no such thing with the first one.

[enectromess]

hi, with new firmware v00.06.03.02.02 2021-10-20 my ds1102z-e sometimes don't boot right. (I think the cause is new firmware but I'm not sure) I have to measure voltages at the connector. Work in progress.

[enectromess]

Voltages seem ok. PSU is based on LD7575 (current-mode PWM controller) + 2SK3569 (power mosfet) also PCB seems quite neat. well welded and well made   

[enectromess]

Seems to be solved. Opened and washed main board with Isopropyl alcohol, recalibrated and a break-in of eight hours always on. 
Seems to be ok. I appreciated the cleanliness and assembly of the components on pcb. Not expensive but really well contructed. 

[Piton]

Interestingly, maybe in my situation it is worth washing the board, especially since there is a suitable moment - I will change the encoder.

[Erikkssen]

Greetings, note that in oscilloscope mainboard there are no electrolytic capacitors. Instead there are tantalum polymer capacitors. Someone says that those are not so reliable as electrolytics.    (compare with keysigh teardown and others)

[Fungus]

Someone says that those are not so reliable as electrolytics.

Who says that?

Electrolytics are almost guaranteed to dry up with age, those are probably more reliable.

Hello,

i am a little confused.

The input can messure up to 300v.
The probe can 1:1 and 1:10.

Can i messure 3kv with this RIGOL or just 300V ??
Because the instruction says the Probe can just 300 volts ?

[Fungus]

Can i messure 3kv with this RIGOL

You can if you get a properly rated high-voltage probe.

The standard ones won't do it.

[TurboTom]

Only make sure you never accidentally activate AC mode on that channel. The probe utilizes the 1MOhm input resistance of the scope as part of the voltage divider. If this is galvanically isolated by a capacitor, application of a high DC voltage will completely drop across the scope's DC block capacitor which may break down (actually, probably something much less troublesome will happen -- the COSMO semiconductor relay that's intalled to bypass the capacitor will zener break down and limit the voltage across the cap, most likely without any damage). But in general, this may lead to a potentially dangerous situation, especially if the DC block bypass is arranged as an electromechanical relay or a plain old switch in the particular scope in use...

[DragonTHB]

Thank you for your answers.

[DragonTHB]

Thank you for your answers.
I just want's to measure 400 volts.
That means when i buy a probe with 10:1 that can handle more than 400volt. Then i get no problem.
I don't know if i should buy this Rigol or a FNIRSI 1014D. But i guess i will buy the Rigol.

[Fungus]

That means when i buy a probe with 10:1 that can handle more than 400volt. Then i get no problem.

I'd buy a fixed 10x probe just to be sure (ie. no little switch to switch to 1x).

Or even a fixed 100x probe, they're much easier to find than 10x probes and usually have a higher voltage rating.

Hello,
With my DS1102Z-E scope, the brightness of the waveform decreases sharply when the time base is 5ns. At 10 ns and above or at 2 ns, the brightness is normal, strange!
Do you have this problem with this scope or have you heard of this problem?
The firmware version is 00.06.3 SP2 and board version 0.0.1
Do you think it's a hardware problem with this board version?
Bye

[lexvts]

Hello! A similar situation, even saves a picture with the same dim beam, in the PC program the beam for 5Ns is already normal. More likely, it's the firmware. The support service is not responding.

This isn't a CRT. Trace brightness is done in software.

Hello,

I own a brand new DS1102Z-E since a few weeks and tried to replace this horrible, non-indexed multipurpose encoder. I found the Bourns PEC11R-4215F-S0024 (24 positions) recommended at a german youtube channel, which is nicely indexed. But with this encoder the Scope always triggers the menu twice, so it jumps over one menu item .

Any other suggestions for the correct encoder? The Alps that is often discussed seems to be discontinued. It should be for SMD mount, but thats not mandatory.

Thanks in advance!

Hello. I also tried cheap Chinese encoders of the EC11 series, but they do not work well, skip and jump. Bought at local store EC11J1524413. Works as it should, but is a bit stiff when shifting and needs some mechanical tweaking.

Hello,
So I'm not the only one having this problem. I contacted Rigol, 1 year ago (October 2021) and they told me that it is a software problem...
I received my scope in September 2021 with firmware version 00.06.02.
The brightness problem with the 5ns timebase already existed with this version.
Updating with firmware V00.06.03 did not solve the problem.

Version 00.06.02 dates from October 2019, information written in the Release Notes.
So the problem exists since this version and maybe even since the conception of this scope.

At least 3 years after V00.06.02, Rigol still hasn't solved the problem and some people on the forum (maybe working at Rigol company) say it's a software problem!!! Easy to keep users waiting forever.

But why the defect has still not been resolved for so long:
First possibility: Rigol is a small company with few incompetent developers and they don't have time to solve a 3 years old bug?
Second possibility: the problem is hardware with board version 0.0.1. It cannot be solved without a hardware upgrade!

Regards

[Piton]

Yes, there are two problems in this model: the shift of the rays when the second channel is turned on / off, which I already mentioned here, and this one with a brightness of 5 ns. Rigol has not responded in any way yet.

[PatrickB]

Hi Piton,
I tried again to reproduce the first problem you mention.
When I validate or invalidate the second channel, the trace does not move. I do not hear the contacts of a relay sticking or unsticking
Maybe I misunderstood the problem.
When you see this problem, what is the value in volt/cm of the channels, is there a signal on the 2 channels?
I'm just trying to reproduce the problem on my scope with your settings.

[Piton]

The problem is clearly visible at maximum vertical sensitivity (starting from 5mV/div.). When the second channel is turned on, both beams move upwards. To return the beams to "Zero", you need to switch both channels to the "Ground" mode and back, then both beams are combined into one "zero" line. Many people have this problem, maybe you are lucky.
  Yes, and at the same time, a relay clicks on the second channel. There is one more point: when the second channel is turned off, the voltmeter readings are absent, and in the first channel, when it is turned off, they remain the same as they were before the turn off.

[PatrickB]

With the sensitivity of both channels set to 2mV/div and without connected probes, when I enable channel 2, the trace of both channels move up at 0.4mV (1/5 of div), no more.
By disable channel 1, the trace of 2 remains at 0.4mV but by disable 2, the trace of 1 goes down to ground.

I had never seen this defect, I don't use my scope with such low voltage signals.

For my use of this scope, the biggest problem is the loss of luminosity with the time base at 5ns. If I get any information about this bug, I'll let you know.

[Piton]

Yes, if you do not use such sensitivity, then this problem can be overlooked.

[RogerG]

You have received the information: "Manufacturing knows this. Whether they will fix it is hard to say."
A software problem can be solved relatively quickly. But it's been around for almost 3 years
A hardware design defect is difficult to resolve without a return to the factory. This may be why Rigol does not give a date to bring a solution to this problem.
I also wrote to Rigol in China 15 days ago. They answered me : "We will check the status of this case and get you back ASAP."

Got mine 2 weeks ago. I bought it knowing about the 5ns timebase issue, TBH its not as bad as I expected. I only need 2 channels and for the price I think its a very good scope for hobby use. Fan noise is a bit higher than I'd like, my only real grumble.

DS1x02Z-E owners, do the following manipulation:
- apply a sinusoidal signal (or other) of 10MHz or 20MHz on both channels

Watch the videos on https://www.dropbox.com/scl/fo/9els7w9e8dfxifkrp9bcj/h?dl=0&rlkey=t6g6y4lli5cviuu50as7yxx2n
With the first video, you will see with which scope settings (10ns, 6kpts and 10MHz signal on both channels), the flickering of the traces appears or not.
In the second, you will see that this problem is visible with certain signal frequencies on the 2 channels.
Of course if the brightness is at 100%, you may not see this bug but it exists nevertheless.

[PatrickB]

Have you noticed the same faults on your RIGOL DS1000Z-E oscilloscopes?
Of course if you have 100% brightness, you won't see them.

trmntr:
Yes, Rigal refunded me the full purchase price.
I will buy a Siglent, the SDS1104X-E or SDS1204X-E. I don't really need the 200MHz. I have not found similar models, which suit me, in the Rigol range.
These 2 models are more expensive than the Rigol.
But Santa Claus is coming soon, I am thinking.


rsjsouza:
The flickering/flickering of the traces was, according to Rigol, an electronic failure.
Fortunately, this failure does not occur on the entire DS1x02Z-E range.


I had no luck with this failure but what prompted me to return my oscilloscope was the loss of luminosity with the time base at 5ns.
I still think that the DS1x02Z-E range is a good entry level at a very correct price, content of the possibilities of this device and that it is suitable for many users. Unfortunately for the use that I have, this defect is very annoying for me.

Yes, I got it and it has 12 clicks, I assumed it had the same number of pulses. And if so, then judging by your previous message, where an encoder with 12 pulses approached you, I concluded that this one should also work regardless of the number of clicks.

[trmntr]

I was not careful when buying this encoder. Having studied the documentation for it more thoroughly, I saw that it has 12 clicks and 12 or 24 impulses.

3 = 12 Detents (12, 24 pulses)

Am I understanding the information below correctly from the screenshot?

[trmntr]

Sure, I'm going to buy a new oscilloscope and I'll let you know my impressions.

Hello.  How are you? you get a new scope?

[PatrickB]

Hello tmntr,

It's been 3 weeks since I received my Siglent SDS1204X-E to replace the DS1102Z-E that I sent back to Rigol.
I bought it from an authorized Siglent dealer not far from my home, unlike the Rigol which came from Germany. This proximity seems important to me following my bad experience with the DS1102Z-E.

It is difficult to compare these 2 scopes, 4 channels against 2, 200MHz against 100, and other functions that do not exist on the Rigol (hence the significant price difference).

With the Siglent, there is no loss of luminosity, even during the displacement of the traces on the screen and even with the time base at 5ns unlike the Rigol. This is normal operation.
The action on the buttons and encoders is immediate. The Siglent encoders have a normal sensitivity unlike those of the Rigol and mainly the one that adjusts the brightness of the screen on the Rigol. Since the years that this scope exists, Rigol could have improved it even if some defects can never be solved.
Having used a digital Tektro for many years, the faults of the Rigol DS1102Z-E bothered me a lot.
The Siglent has an integrated http server which allows it to be controlled and to export the traces. It saved me from developing software in C# as I had been able to do for my Rigol and my Tektro.

I recognize that this Rigol DS1102Z-E has an interesting performance/price ratio and should be suitable for many amateurs who are not too demanding.

So why this Siglent? How can you be sure that it corresponds to what is expected of this device?
The best is to know a user to have his objective opinion. And in case of acquisition, to have a period (normally 15 days) to try it and in case of dissatisfaction to send it back and get a refund.

In short, I am delighted with the purchase of this SIglent SDS1204X-E scope, I do not regret this change of oscilloscope, even with a price difference of almost 3 times.

Hi!
Who knows what is the difference between HW version 0.0.1 and version 0.0.13? What significant improvements does the oscilloscope have with motherboard version 0.0.13?

[Fungus]

Who says it has to have "improvements "?

Most likely just component substitutions because of global shortages.

[PatrickB]

Or probably just to solve the hardware defects of this scope.

The loss of brightness and other problems reported in this forum by users are not software problems as Rigol and others have told me.
This scope was put on the market in 2019 (date of the first version of the software) and even with the different versions of the software the defects were not solved.
If for 4 years, the engineers have not solved the problem, is that they are bad? No, because producing scopes with a BW of several GHz is not easy. And if it's not a software problem, it's a hardware problem.
Knowing the difference between hardware version 0.0.1 and 0.0.13 also seems interesting for users future buyers.

Just when new firmware comes out, they have a description of what has been changed or fixed.  But there is no information anywhere about what has been improved or fixed in the latest (possibly the latest) hardware version.
On the one hand, if a manufacturer makes changes to its product and this is not a correction of an old error in the board layout, but an upgrade, then this is understandable, but when three years have passed since the launch of this sight on the market and when you buy a device, you get the first version of hardware  with a possible flaw in the circuit, it becomes a little unpleasant)

I tried to do Self-Cal, it writes "Disconnect everything from all inputs!" And progress bar doesn't move.

Hello everyone.
Just get my DS1102Z-E. It doesn't show signal lines. Both channels are ON, but it looks like it doesn't feel any trigger signal.

Maybe it's set to external trigger.

I tried to do Self-Cal, it writes "Disconnect everything from all inputs!" And progress bar doesn't move.

But that sounds bad.

Could it be a software glitch?  Do a factory reset.

trmntr is right, a factory reset might solve your problem.

On the Rigol, which I had, it was impossible to reinstall the latest version of the software after trying older versions.
At each attempt to reinstall the latest software version, the scope displayed "Update was failure". 
To perform a hard reset, I had received from Rigol the following procedure and it worked, the latest software version could be reinstalled:

"Put latest firmware on to the root directory of a jump drive formatted to FAT32. The newest firmware can be downloaded from https://www.rigolna.com/firmware/.
While the device is off, insert the drive into the USB port in the front. Start repeatedly mashing the "Help" button and power up the unit while continuing to press the button repeatedly. This should cause the device to try to boot from the external drive with the new firmware. If the firmware is loaded successfully, the instrument should not boot into the red screen error, but it will remain unresponsive while the firmware is installed - this can take up to a few minutes."

At the end of this long procedure, the messages displayed are in Chinese languages but the button to change languages automatically appears on the right of the screen. It's good.

Hi!

I found one bug in the operation of the oscilloscope and I would like you to check it for yourself in order to understand it only for me or for all Rigol of this series ...
 Turn on the device, turn on one or two channels.  On the left side of the menu, select measurements for the channel, for example, Vpp.  In the Measure menu where Font size choose Large or Extra Large.  Go back a little now to Statistic and slowly toggle this between ON and OFF.  In this case, the selected Vpp parameter will switch to the extended window and back.  At some point (no more than a minute), the device freezes, stops responding to the buttons.  Beam settings can still be changed with encoders, but no correct parameters are displayed on the screen.

Hello. It doesn't freeze in my auto mode. In the "Normal" mode, it does not freeze immediately, but in single mode - immediately to a black screen.

Take a short video.  I have the same behavior in all three modes.

Hello,

I own a brand new DS1102Z-E since a few weeks and tried to replace this horrible, non-indexed multipurpose encoder. I found the Bourns PEC11R-4215F-S0024 (24 positions) but with this encoder the Scope always triggers the menu twice, so it jumps over one menu item .

Any other suggestions for the correct encoder?

Presumably you want the one with less pulses:  Bourns PEC11R-4215F-S0012

Hello.  I tried replacing the native encoder with another one with 12 clicks and 12 pulses.  If you do not rotate quickly, the menu bar jumps two positions.  Do I understand correctly that for correct operation me will need an encoder with a number of pulses that will be half as many clicks?
