I'll send you my address for the bottle. I trust you to pick something nice.
Please do, I am a man of my word.

Indeed. Come to think of it, I don't think I've ever used a non 7-bit I²C part in anger in the past 32 years as an EE. I completely forgot about the extended addressing.

Anyway, a fine bottle of scotch will find it's way to Croatia as soon as it knows where to go. :-+

My friend,
I was just joking. There is no need for it, really.
My biggest reward is that I could help. Really, pleasure is all mine.

That does not mean, that if you ever pass through Rijeka, Croatia, let me know, and we can have a sit down a have a proper drink!

As for 10 bit I2C, I never used one either... But I encountered one on some device once. And I was confused that Keysight didn't do it properly. Luckily, my trusty Pico did....

My best,
Siniša

@BreakingOhmsLaw I suggest you to revise points #2 and #7.
On #2 clearly is not a bug. Veteran 66has explained why. If we using a Linux share we need to use this format.
On #7 you need to see if this incident can be reproduced. Usually an incident that can't be reproduced can't be called a bug. There were a few others incidents that crash the scope but I can't reproduced anymore. But also on all my scopes I encounter this at a moment in time.(Keysight, RTB2K, Micsig, Rigol).
Did you tried to reset to factory default, Secure erase, before reinstall the firmware?

New Firmware for 1000X HD - 1.1.3.8
I did not find 1.1.3.6 even on Chinese site, maybe in new units from factory.

2024/06/14
1.1.3.8
1. Optimize UI, change "on/off" to "On/Off".
2. Solve the problem that some numbers from 200-223 cannot be entered in the first byte of the IP address.
3. Standard software functions of FG and LA.

2024/05/22
1.1.3.6
1. Solve the problem of trigger holdoff fails.
2. Solve the problem of CAN decoding causing crashes with a small probability. 3. Modify the kernel s olve the problem that scpi cannot be
used on a computer with keysight driver installed
4. Solve the problem of advanced trigger (Qualified, Nth
Edge, Delay, Setup/Hold) parameters are not recalled.
5. Solve the problem of delay trigger level setting error.
6. Solve the problem of when the edge is set to Alternating, trigger jitter will occur when entering the other trigger type.
7. Solve some known problems.
8. Optimize waveform capture rate.

9. Optimize self calibration speed.

That would also be something for the SDS3000X HD.
If you start the Self-Cal there, you can confidently go shopping, vacuum the apartment, make dinner... ;)

It's take about 5 minutes now.
Also waveform update does not seem to be faster, but I will keep measure in future.

L.E. In dots mode I have obtained 128 K.

The information in the data sheet only refers to a "sweet spot", a time base and certain settings anyway.
In the meantime, I've made my peace with it as long as it doesn't drop too much above and below the sweet spot.

I didn't see this listed so I guess my unit is broken  |O

Only channel 2 and only close to 0V vertical offset

Screenshots and a description of settings and how to replicate are more helpful than a video where we can't clearly see the settings.

Default 'll have to wait a few hours (I'm on my dayjob, now).

Settings are:

- all channels DC,
- 1 MOhm,
- 0.5 mv/div,
- 0V vertical offset (except for the moves I made in the video to offset C2 over and under 0 by a few hundreds microvolts),
- trigger is rising slope on C2 level + 400/500 microvolts. If I trigger on any other channel I get no events.

if I move the offset under or over 0V the spike disappears.

This happens more frequently after switching it on and becomes somewhat less frequent after a few hours of power on. 

If I set C2 to AC it still happens but way less frequently, I even captured a single event while on GND.

The size of the spike is dependent on how many other channels are turned on. If I have only C2 or only 2 channels on the height of the spike is way lesser (but still captured by that trigger setting).

All other channels appear flawless.

Ch2 was set to Trigger so at max sensitivity you're triggering on noise.....nothing to worry about and the reason you are only seeing it on Ch2.
In the channel menu engage the 20 MHz BW filter and it will be gone...

By setting the trigger on other channels (all other settings being equal) I've never seen *any* single spike. So no it is definitely something that's happening on the input circuitry of C2

AFAIR setting 20MHz BW doesn't eliminate the problem (confirmation this evening)

Okay, good info.

Ok so I defaulted and  self-calibrated it.

Some new "features":

- only when C2 is off then spikes appearing also on C1, when C2 is on then it "takes it over" all the spikes.
- more notably now I'm on 10 mV/div scales and trigger i set to 6 mV
- as usual spikes only when channel postion is close to 0

Can I ask if this is observed with open inputs or with probes connected ?

About to do some checks with a unit I have here in case what you see is some local RFI/EMI at your bench.  :-//

Can't replicate your results.

Open inputs tests
With a Single trigger I can trigger on noise at low level trigger settings, under ~250uV.

Some screenshots attached.
#5png is a Single trigger setup waiting for a peak that never arrives at those trigger levels.

All I can suggest is to investigate local RFI noise.....these can even be from some device in an adjacent room.

If they were interferences:

- they would show up at any vertical offset of the channel an not only close to zero
- they would show up not only on ch2 an to a lesser extent on ch1 (that if I’m not wrong share the same ADC and therefore some input circuitry) but also on ch3 and ch4.
- their amplitude would be independent from the vertical scale (of that i’m not so sure if the enter after gain stage, but it is a strange point of attack for RFI, much less likely the front end in my opinion). I observe the same amplitude on screen on both 0.5 and 10 mV/div.
- they would be detected by old trusty 1104X-E

I also moved to the opposite side of the flat to no avail, so it would have been a very pervasive  RFI but yes this one is not conclusive.

All of that points to a defect in the input pipeline of only 2 channels ,after front end just before ADC. As it is a subtle effect it may have escaped quality control.


Let’s see when assistance reaches back to me what they’re gonna say.

Today I got an SDS1204X HD (fw version 1.1.3.8  ) and also a SAG1021I arb. Appreciate any guidance on a few puzzles (yes, I did RTFM):

1. Product page says you need a separate license to enable the wavegen, in addition to buying the hardware. It works out of the box; is this a ‘temporary’ license that evaporates? Like to know up front if they are going to brick it and soak me for more $ after the return window lapses. 

2. Any graceful way to abort a Bode plot during the sweep? Unresponsive while sweeping, and if you selected “Continuous” it loops indefinitely. Only thing I figured out is to fully exit Bode mode altogether, at which point it forgets the setup and reverts to (useless) default sweep parameters.  Hope I’m missing something simple here.

3. Which brings up,  is it possible to save the Bode configuration, or at least have it come up in the last configuration used?  Can any instrument states/setups be saved/recalled?

4. FFT is pretty good, but again, a way to save/recall setups (and even apply them to a new channel) would be helpful. I can do FFT’s on two channels at once, but the display does very stupid things if I show them together, unless I manually enter all possible settings exactly the same for each channel.

Incidentally, the scope should have plenty of grunt to do 2-channel cross spectrum, coherence and Fourier frequency response, and evidently bit depth and front end noise to make them count; is that too much to ask?

5. Somehow I imagined they’d send me compatible 10x probes with a 200MHz scope advertised to have auto probe detect. The PP215 probes they sent are switchable 1x/10x toys with no signaling pin. Very disappointing.  I had to dig out some ancient Tek P6106’s from the 1970s.  (Yes, probe detect does work, with _real_ probes.)

Happy for any wisdom you all can share. Don't get me wrong, I'm very pleased so far; a far cry from my last experience with Siglent. One day in, this appears to be an excellent tool.  Thus, worth making better.

Cheers,

zike

The need for FG and LA option licensing was deleted in the latest FW.

Intuitively Run/Stop should cease the sweep...not sure so check.
IIRC in one of the Bode plot menus you can also stop the sweep.

Utility>Save/Recall menu allows for Setups to be saved, IIRC 5-10 internally for Recall and infinite when saved externally.

Yup disappoints me 2 but is the same for low BW SDS2000X Plus models also, only PP215 is supplied.

If you want them to include better probes, they'll raise the price. You're better off getting some nice probemaster.com probes.

Thanks for this guidance.  I played with it a bit more and don't find a good way, perhaps I'm looking in the wrong place. It seems bode setup gets forgotten and reset to defaults once you navigate away to access the Save/Recall function. Also,  it appears the saved Setups only include channel, timebase and trigger settings; recalling a Setup file did not appear to restore (or over-write) any of the math functions I had configured, for example.
