How many measurement stats can Rigol display on the screen at the same time? 

Although I did not run into this issue yet as I usually use only two channels, max of 5 measured items on Siglent seems to few for a 4 ch scope...at least 8 would make more sense (2 stats per ch)

EDIT: looks like Rigol displays 5 items also, but Siglent gives more information such as Std-Dev and Count

Yep, it's five.

nb. You can take a quick peek at all the other measurements using the button on the right.



It toggles an overlay, eg.


...and Count
What happens if you press the button labelled "Counter"?

Interesting.  Siglent can display all measurements also, however, only for one channel at a time.  Your example is showing Ch1 and Ch2 at the same time, but waveform is covered up - can transparency be adjusted?




...so, what happens when you press the Counter button?

I don't think so.

It shows the frequency counter.

Does someone tested input impedance of SDS1104X-E with vector signal analyzer?

I have old SDS1102X, and it's input impedance for frequency range 5-85 MHz is the following:



If you want I can take results for other frequency range.
I'm very interested to compare results with other oscilloscope models.

As I understand the probe compensation issue is related to the input impedance mismatch.

Hi,

I recently bought a SDS1104X-E and I really like it so far. Coming from an ancient Philips PM3234 the possibilities of a modern and affordable dso are amazing!
And I don't understand the issues some people have with the UI. I found it rather quick and intuitive to use and I like the clean layout.

The only major bug I've noticed is in the search function. Once the aquisition is stopped, the scope often can't find search events in other channels than the selected one during aquisition. It seems to be somehow related to the channel offset, I have included some screenshots. That really slows down my work, because I often need to single capture multiple channels and search for specific events in them.
Is anyone able to reproduce the bug? (FW: 7.6.1.20 R1)

ps: shout-out to Performa01 for the amazing review and the work he puts into improving the firmware!

...

I’ve already admitted that I did not do a thorough check on the Search function yet and right now I have very little time. Yet I’ve tried to reproduce that odd behavior and there is a bug indeed.

The test was done with two signals:
CH2: sine 5MHz 1.5Vpp
CH4: square 10MHz 1.5Vpp

First Search for rising slope at threshold 0V on channel 4 works as expected:


01 SDS1104X-E Search CH4 Th0V-1


Then the same Search fails on channel 2:


02 SDS1104X-E Search CH2 Th0V


Only after adjusting the threshold way negative, it starts working. The correct result is obtained when the channel 2 threshold level is at its negative maximum:


03 SDS1104X-E Search CH2 Th-nmax


Switching back to channel 1 still works as before:


04 SDS1104X-E Search CH4 Th0V-2


I’ll notify Siglent R&D of this issue.

Stemming from comments and questions about BW roll off I thought I'd offer some screenshots as examples.
Signal: HP 500 MHz sig gen and BNC connection.

SDS1104X-E just where waveform amplitude begins to reduce but still above -3dB BW




SDS1104X-E where the frequency counter starts to become unstable and waveform amplitude dramatically reduced.




SDS1202X-E, as for SDS1104X-E above, frequency counter starts to become unstable and waveform amplitude dramatically reduced. One might presume SDS1204X-E will produce identical results.

@tautech, could you run the same test but with PP215 probe and SDS1104X-E?

Sorry I don't have the 2ch SDS1102X+ older model any more, recently sold including 16ch MSO option.

The above link is for the 7.6.1.20R1 firmware. The new firmware is missing on the Siglent America webpage.

Use this link for now:

https://www.siglenteu.com/download/5931/

EDIT: all update files are available on Siglent America webpage now too.  :-+

Hi, I have a SDS-1104X-E and I'm very happy with it.

My software version is the original 7.6.1.12R1, do you advice to update even if I don't have significant problems with it?

What is the correct procedure? I have to update the OS and the firmware togheter?
