The Siglent SDG2042X Thread

[McBryce]

Had a strange one at the weekend with my SDG2042X (latest Firmware). I had it hooked up to a small test circuit I use for designing filters, with the output of the filter (simple LC filter) connected to a scope, terminated with 50ohms at the scope input. The FG was outputing a 1Vp-p 25Mhz square wave 50% Dutycycle (no sweep / offsets or anything else). All worked fine at the start, but after about 10 minutes the trace suddenly disappeared from the scope. The filter was fine, so I connected the FG directly to the scope and the FG output really was gone? I turned off the FG and restarted, but still no trace. Turned off again and waited 10 minutes, then the output was back.
It wasn't warm in the room, so I doubt it was a heat issue, but something resettable inside had decided to switch off. Has anyone else seen this happen?

McBryce.

P.s. The filter was a 20Mhz to 30Mhz bandpass filter, so yes, the signal (most of it) should have been getting through

@ McBryce
I've linked Siglent to your post but it's AHrs in Shenzhen now.

From the manual P125
Overvoltage Protection

If the state is set to ON, overvoltage protection of CH1 and CH2 will take effect once any of the following conditions is met. When overvoltage protection occurs, a message will be displayed and the output is disabled.
 The absolute value of input voltage is higher than 11V±0.5V when the amplitude of the generator is higher than or equal to 3.2Vpp or the DC offset is higher than or equal to |2VDC|.
 The absolute value of input voltage is higher than 4V±0.5V when the amplitude of the generator is lower than 3.2Vpp or the DC offset is lower than |2VDC|.

All I can offer/suggest depends on how your LC filter was configured and then maybe back EMF might have been the culprit. 
Other than that I'm scratching my head as you are. 

[McBryce]

Strange, now that you mention it, it very quickly displayed something about over-voltage when I turned it on (just before the error occurred), but there was nothing connected to either of the outputs at the time, not even a loose cable. Both outputs still worked for about 20 minutes after that.

@ McBryce
Please keep us informed if there any more problems with this ^^^

If the problem repeats itself you could try disabling the overvoltage protection but it's there to protect the outputs from damage so remember you've done so if the FG outputs are likely to be exposed to any voltages. eg. injecting a test signal into the mid stages of an amplifier etc.

I'll give it a few tests over the next few days and let you know if it re-occurs. Is there a quick "return device to factory default settings" method, so that I can test the device from a know condition?

Hi McBryce.

You can reset the SDG2000X generators to factory default by pressing the "Utility" button then "System" on the menu, then "Set to Default".

Anyone have any tricks for this problem?

https://www.eevblog.com/forum/testgear/sdg2042x-triggering-both-channels-at-the-same-time-in-burst-mode/

Functionality I need,

CH.1 to burst with X delay @ Y frequency with Z cycles/Burst period

CH.2 to burst with A delay @ B frequency with C cycles/Burst period

Both channels must trigger from the same external/manual trigger

A bit of an update.

Firmware P21R2 fixes the issue of triggering both channels in burst mode from an external trigger.

Triggering both channels from a manual/software trigger remains unresolved. I've talked to Scott and he is relaying my issue to the factory. Hopefully there will be a new firmware update that patches this up.

Hi,

I just got my SDG2042X. Updated to latest firmware and seems to work just fine.

When reading the remote command manual I didn't notice any way to upload ARB data via the SCPI commands. Not a nice surprise. Am I missing something?

Is there a workaround?

Hi McBryce.

Quick update: I've been using the SDG2042X extensively for the last 2 weeks and the error hasn't occurred again so far.

I found this:

I will experiment and get back to you if I run into problems. Thanks!

I've been looking for a proper waveform generator to replace the function generator I built. The SDG2042X looks like the best inexpensive waveform generator currently available, but I'm hesitant because TEquipment doesn't even keep it in stock anymore. Does anyone know what's going on with that? Is Siglent planning on replacing the SDG2042X soon, to anyone's knowledge?

Saelig are now handling Siglent and offer the same discounts:

Post in that thread for the code. 

There's also a lower priced new AWG from Siglent if you don't need the BW the SDG2kX series offers:
SDG1000X series, 2 models, 30 or 60 MHz

Thanks. I'll check out that SDG1000X series, it might work just as well for my purposes.

Greetings to all,
I am a true Newbie and I'm trying to do the editing software to get to 120MHz with Siglent SDG2042x.
The whole procedure works ... but when it comes to ESC (after deleting the line <LICENSE>) the cursor does not go to the bottom and I can not write WQ......
You can kindly help me?
Thank you all.

Since it does sound like you are editing the file with VI, after you have deleted the line, you need to press SHIFT-COLON, ":". Then "wq". Thats why you see the command as ":wq". The colon is significant and required.

Hi,

decided to buy one after reading this thread (the best advertising...), and received mine this day. First test, and seems to be very good for the price. It will be used for testing signal processing, I/Q modulator and demodulator... Next step is to upload waveforms, if possible created with Scilab.

I have done the work and now my Siglent became SDG2122X.
But I can not install the USB drivers for EasyWave.
Can someone help me?
Thanks

Updating

I've install the driver usb but EasyWave don't see the SDG2122X
