The new FW (6.1.35R2) has changed the way the screen is displayed via the website. It is now on the same page and you do not need to use the back button to e.g. issue the SCPI command. I didn't notice this in the list of changes ...
Is it possible to calibrate the internal time base or frequency display? my SDS 1104X-E always shows only 9.99995 MHz at an exact frequency (10MHz GPSDO)!
Same here, on the sds2000x+.
I think it´s a "digit problem", which means it´s not a real problem but a "natural" matter of fact.
Hi there
Can anyone explain the meaning of the beep when starting the SDS 1104X-E?
My device sometimes beeps twice at startup? (Firmware version: V6.1.35R2)

I think it's because of the inaccuracy of the internal TCXO
Timebase accuracy sds1000x-e 25ppm, siglent sds2000x+ 1ppm...
Best guess: a test beep since it does have a speaker inside of it.

It's like a POST test but if you don't like it in Utilities you can turn the sound OFF. Use Default and it will be back unless you make your personal Default settings and save then using the Set to Default feature in the Save/Recall menu.

the 2x beep is due to the new firmware, V6.1.33 is not !
New Firmware https://int.siglent.com/download/firmwares/?ProId=12
Version: V6.1.35R2
Since this is the first new firmware since I "upgraded" my 1104X-E to a 1204X-E, can anyone tell me if doing this firmware upgrade has any effect on that or any other unlocked features?
My hacked 1104X-E still keep all options permanently enabled after firmware update ( not hacked to 1204X-E yet, only wifi, awg and mso )
Hacked my BW and options. Still there after FW update.
Ok I went for it and all “upgrades” remain. 👍
I'm not sure if this is a bug or me not knowing how to use this scope but I'm trying to zoom in on a specific spot of the waveform that I have centered on the screen in the 1st attachment. That's 1V/div 500us/div on the test signal in front of the scope. .
I've got the reference POS in Fixed Offset-Vertical and Fixed Position-Horizontal
When I zoom in to 100mV I get the second attachment and now I'm looking at some middle bit of the wave. 500mV and 200mV worked fine and took me closer to the plateau of the wave. I've tried different combinations but still wind up in the middle. Am I doing something wrong here?
Don't know why this didn't attach. This is the starting point.
Figured it out. Had my probe at 1x.
I'd like to understand how the internal frequency counter works. I measured an SPI clock of 10MHz. The measurements show a perfect frequency value but the frequency counter shows
<10Hz. Why? What am I missing?

The inbuilt frequency counter is for continuous waveforms for the channel selected to provide the trigger.
How you are using the dedicated channel measurement is correct.
I found a mismatch between channels in my unit. On the attached screenshot is shown the same waveform sampled on two different channels. Both are sampled with the original Siglent 200MHz probes in 1X mode connected in parallel. On channel 4 the measured maximum is higher than on channel 2. The tested circuit is powered with Vcc=3.31V measured. The maximum value of 3.48V on channel 4 is 5.14% higher than the expected 3.31V which is much higher than the 3% stated in the datasheet. I tried to replace the probes with BNC-hook cables and got the same results. What can be the problem? What am I missing?
How are the versions of Siglent manuals numbered? For example, I have oscilloscope manuals versions UM0101X-E02A, UM0201X-E01D and UM0101E-E03C. How can I know which one is the latest?
Have you run self calibration on your unit?
Yes. Did it twice after a version update some days ago.
Try switching the probes (1->4, 4->1). I have 10% difference on my scope, switching the probes switches the measurements as well (4V CH1, 4.4V CH4 --> 4.4V CH1, 4V CH4)
I tried. Still get the same results.
Have you tried different vertical measurements besides MAX?
Probes calibrated to the channels? My channel 2 probe will read different if I put it on a different channel. Not a huge difference but it's there.
