Title: Rigol DS2000 Hardware version 2.0
Post by: PA0PBZ on July 31, 2013, 08:20:11 pm
This is a DS2072 (or more a DS2202 now) with version 2.0 hardware.
Looks like they are going to use the empty spot in the version 1 hardware to make a D model with Logic Analyzer included, and while they were designing the new pcb the input channels got reworked too. Unfortunately it doesn't look like something you can populate at home...

Warning, large pictures!

  - Blue: Add, I do not know what is, but I have an idea (A kind of comparator / level translator or a simple digital buffer).  :-//

  - There are also changes in the DC/DC power, it look better, but these changes will introduce less noise?
     What is behind, in the other side of the pcb? And I am not sure, but I think there are also changes in the PSU.  :-//

  - To the input stage has been added a 50 ohm terminator (and other relay).  :-+



Wow, they had designed it before the 2012/10/29.
LA connector is a PCI-E!



Thanks for the pictures to David L. Jones and PA0PBZ

PA0PBZ, you can select the 50 Ohm option?
Can you upload an image of the LA zone with more resolution?
I assume that this new version will have a new "line" for firmware.

It seems that I write this post myself, LOL, but:

I've noticed that with the series DS2A1527XXXXX RIGOL not only changed the probes.

No, it is on the screen in the CH menu but it is fixed at 1M. Not surprisingly because the firmware is the same as the version 1 hardware.

Yes, I will do that when I get home tonight. The scope is still in exploded view.  ;)

Although it looks like there is a 50 Ohm termination in the input channel now, it is not selectable in the menu, it is greyed out.

There are changes in the PSU to, but are minimal.
I wonder what's behind the mainboard, but surely there are others eight channels for the LA, at least the traces from the connector to what looks like a comparator.

I do not know, but at the moment it only has a stub at the input. But I don't think that it affects for a BW of 200 MHz.

Maybe, but the models are not on the market yet so there will be no firmware available, this one still runs on the hardware version 1 firmware. I wonder if you have the same non-functional 1M input button on that hardware...?

Yes, my HW version 1.0.1.0.0, is also fixed to 1M.

Now, this is my doubt:  Anyone know how many versions of HW exist until today's date?
And if this sequence of HW is correct (1.0 -> 1.0.1.0.0 -> 2.0), have the 1.0.1.0.0 version the internal 50 ohm termination too?



Okay I think I have the answer, just two HW version: 1.0.1.0.0 -> 2.0.
And I have the feeling that in the 2.0 Ver. they have improved the PSU and DC/DC parts.

After reviewing the new main board for RIGOL DS2000 (HW Ver. 2.0). I think than this M.B is valid for, DS2000-S, DS2000-D, and then too for a possible DS2000-[DS or SD or ?] (ie whit LA and Function Gen.).

Interesting, there is something about 50 Ohm and 1M ohm in the latest firmware, however on screen it shows the Ohm symbol, not the tekst 'Ohm'

This is a comparison between the two hardware versions.
Type of test: Noise floor.
Results for hardware ver. 1.0.1.0.0:

(1):

1. Oscilloscope turn on time ~ 30 minutes, and away from sources of interference.
2. No probe connected in any channel and, only CH1 on.
3. Setting: Full BW, Vector, 1mV/DIV (x1), DC,  Adquire=Normal, Men.=Auto, Persistence=inf., Base time=500us, Trigger level=0V.
4. Cursor on, mode Y, after five minutes of measurement with persistence=inf. set cursor to the maximum.


(2):

1. Oscilloscope turn on time ~ 30 minutes, and away from sources of interference.
2. No probe connected in any channel and only CH1 on.
3. Setting: Full BW, Vector, 1mV/DIV (x1), DC,  Adquire=Normal, Men.=Auto, Persistence=inf., Base time=2ns, Trigger level=between 500uV and 600uV
4. Cursor on, mode Y, after five minutes of measurement with persistence=inf. set cursor to the maximum.

In red, trigger level, find the worst case.

Hi,

My result for (1) is the same, just a little bit less amplitude.

For (2) I can't set the trigger higher than 400uV otherwise it does not trigger. When measuring the top cursor is at 600uV, the bottom one at -700uV so total 1.3mV

Still fooling around with the 50 Ohm option, found this SCPI in the firmware:

Code: [Select]
.RES.DATA....CHANnel.CHAN....BWLimi
t.BWL.BWLimit?....BWL?....COUPling.
...COUP....COUPling?...COUP?...IMPe
dance...IMP.IMPedance?..IMP?....SCA

:CHAN1:IMP? returns 0MEG, and I have not found a way to change it via SCPI, tried several variations of CHAN1:IMP 50... but nothing.

I will as soon as I hook it up again, but the return value of 0MEG doesn't give much hope anyway.

I will as soon as I hook it up again, but the return value of 0MEG doesn't give much hope anyway.

it is "OMEG", not "0MEG" and it is exactly what the firmware have to return. The "FIFTY" is another one possible value in the firmware.

Yes, it is 0MEG, but if it was a working command it should have returned 1MEG isn't it?
Title: Re: Rigol DS2000 Hardware version 2.0
Post by: tinhead on August 05, 2013, 10:13:18 pm
it will return what has been coded into the firmware, and when you look inside you will find "OMEG" and "FIFTY".
The "O" in "OMEG" menas nothing else than "one", so everything fine. Sure, 1MEG could be good as well, but the number "1" in string is probably what they tried to avoid.

I would like to work on this, but nobody seems interested in doing a JTAG dump of fw nor helping me get some working binaries of the blackfin IDA parts (cybernet likely has them, I can't compile them by instruction, the closest I got was with VS2008 but the resulting binaries didn't work). There may be a menu or config file to set this but without being able to work with the fw, I can't do shit.

Or if you prefer the other channel: CHAN2: ...

Seems do-able to stuff a relay and resistor at the input, but what circuit do the switching??
Not having 50 ohm on my new scope is like have a pebble in my shoe  :'(

Not having 50 ohm on my new scope is like have a pebble in my shoe  :'(

But honestly could just do as good with a 50 ohm feed thru load.

Seriously just buy 50 ohm terminators.  Sure it sucks but it's hardly a problem.

Paul, where did you get your scope from??
When I asked my supplier why I got a rev 1, he said Rigol.eu did not have any v2 in stock and did not know when it would ship!

I bought it locally on July 30, when I called them they said they just had a new shipment in. The sticker on the box says it was shipped from Rigol EU in Germany on the 25th.

PA0PBZ,

Are you able to measure the actual input impedance of the V2.0 hardware in 50 ohm mode, using a VNA or some other suitable tool, please?

The original input is 1M || 16pF, and if they just slapped the 50 ohm across the input, then the 16 pF may still be there. That would create a rather wonky impedance mismatch above 50 MHz or so, not good in many situations.

Post by: PA0PBZ on August 19, 2013, 12:15:20 pm
Unfortunately I don't have a VNA, only a scalar one. But I can do a return loss on my SA, see the attachment.

Thanks, that should do nicely. :-+

However, if my algebra isn't completely off, then it very much looks like Rigol simply connects a 50 ohm resistor across the input, as you would expect. If we assume the real parts of the load and source impedances are both 50 ohm, and with no reactances in the source impedance, then I get an input impedance of about 50 -j29 ohm at 300MHz. That is equivalent to 50 ohm || 18 pF.

That would make it a bit of a challenge to make a 'flat' active probe design, good to 200 MHz. Hmm, maybe I should buy a DS2072 DS2202 and try to make one... :D

Yeah, from what I see on the frontend pcb it's just a relay switching the 50 ohm resistor across the input, so your math is probably ok. But please keep in mind that it is not possible to switch the input to 50 ohm using the channel menu on the scope, it is not functional yet so who knows what they are up to.
And any excuse to buy one of these will do  :)

Noise floor measurements did not reveal any difference, and even the 50 ohm terminator is not accessible in the normal (menu) way, so I'd say there is no difference at all between the hardware versions for the user. Inside it is a different story, apart from the terminator there is room for the LA and FG on the pcb, so there will probably be S and D models sometime in the future.

DS2000A has a potential for eventual future hardware upgrades. Other than that it's the same.
I ordered old hardware version few days ago and expecting it to arrive in a day or two. I don't need LA and AWG.
I didn't want to wait for a new version.

Yes, DSA9 and the Windows 2.0b1 version of the generator.

I see that DSAZ is recommended as only turns on DS2202 and 200MHz.

DSA9 is not recommended as it turns on both DS2102 and DS2202 plus both 100MHz and 200MHz.

Does anyone know what issues I can expect by having used DSA9 and having "everything" turned on?

And the obvious follow on question ... How would I change it to DSAZ? The obvious answer ... "Generate a new key for DSAZ and enter it." did not appear make any difference to what was displayed in the options as both "BANDWIDTH 100M Bandwidth" and "BANDWIDTH 200M Bandwidth" are displayed. I also tried a key for DSAA in an effort to set it back to a plain Jane 2072 and nothing happened. I am left with the impression that "you can't easily go back".

It seems to have gotten the model part right as the System Info shows "Model: DS2202".

Testimony is not reliable at the range above 20MHz - BW Limit.

I don't really see a problem with the scope here.

A) The waveform in the first 2 pictures looks distorted but that is no surprise looking at where your ground connection is, it should be as short as possible and as close to the probe pin as possible. Look at these little springs you can slide over the probe.

B) The waveform with 20Mhz bandwidth looks better because you filter out the higher frequencies: looking at the top of the waveform in the first picture the extra 'wave' looks like 10ns duration -> 100Mhz.

Thank you for your response PA0PBZ.
But unfortunately the change point of mass does not affect the reading.
As expected, since the mass of laptops is present throughout the system board as one of the layers of a multilayer PCB.
I suspect that the digital input filter was originally set to range up to 70 MHz, and beyond it is working no correctly.
Maybe I'm wrong and this is a common mistake inexperienced users ...

If possible, please make sure that someone in their own terms.

This is a comparison between the two hardware versions.
Type of test: Noise floor.
Results for hardware ver. 1.0.1.0.0:

(1):

1. Oscilloscope turn on time ~ 30 minutes, and away from sources of interference.
2. No probe connected in any channel and, only CH1 on.
3. Setting: Full BW, Vector, 1mV/DIV (x1), DC,  Adquire=Normal, Men.=Auto, Persistence=inf., Base time=500us, Trigger level=0V.
4. Cursor on, mode Y, after five minutes of measurement with persistence=inf. set cursor to the maximum.


(2):

1. Oscilloscope turn on time ~ 30 minutes, and away from sources of interference.
2. No probe connected in any channel and only CH1 on.
3. Setting: Full BW, Vector, 1mV/DIV (x1), DC,  Adquire=Normal, Men.=Auto, Persistence=inf., Base time=2ns, Trigger level=between 500uV and 600uV
4. Cursor on, mode Y, after five minutes of measurement with persistence=inf. set cursor to the maximum.

In red, trigger level, find the worst case.
My results are slightly worse than yours, ~2mV delta for both tests, though I've entered a DSHH key for 300 MHz. I have a trigger hat just like yours too. I have screens if you want to see.
