Noticed phase angle assuming wrong value with dissimilar waveforms. Ch1=square, Ch2=sine. Shift is set to -45° on Ch1, result is ~-55° instead. When switching Ch1 to sine or Arb/DDS square shift assumes correct value. State file and screenshot of result attached. Latest fw.

Edit: Should you ever need sharper rise than default square Arb/DDS one will do it:
Default: 0.35/9.6ns~=36.5MHz
Arb/DDS: 0.35/5.5ns~=63.6MHz

Edit2: Arb/DDS just had favourable setting :( When set 90° get ~86.5°. Screenshot attached. Possibly this has some technical justification.

Edit3: Small unrelated annoyance. When switching CH1<=>CH2 screens it will always switch Frequency|Period to last used on other screen. So if want fiddle only with freq on CH1 and with period on CH2 it's quite a hassle.

Recently bought an SDG2042X and am really impressed so far. Does anyone know of a VI control for these generators? I'd like to be able to do basic control over the instrument via PC.

Thanks!

MotoDan,

I have not used a Labview VI, but I have used Python to control (and calibrate) my SDG2042X.

There's an example of using Labview starting on page 64 of the Siglent SDG programming manual:

Thanks for the info JDubU. What I'm really after is a Windows GUI that comes close to matching the SDG's front panel. Just need a way to change settings via my PC which is located away from my rack of instruments. I use a similar program (M9700) with my Maynuo DC Load.

The closest you'll get IIRC is form within the EasyWave software from Siglent. Not sure if there's a virtual panel for the AWG's like there is for the scopes though, I can check for you later.
Now, with EasyWave you need to install NIVISA Runtime at the least to provide the correct drivers for PC connectivity......be sure to do this first before you connect SDG to a Windows PC otherwise Windows will think it knows best and then install the wrong USB driver.  ::)
Let us know how you go as I can check this in full later.

tautech I have EasyWave installed for my SDG1000 arb gen, and unfortunately, it does not have a virtual remote control panel for the gen (However, I don’t know about how it might work with other models). It does the wave creation and editing, and lets you save locally or upload to the gen (as well as download any of the arb or built in waveforms from the gen). A remote panel would be a great feature, for sure.

I have EasyWave, but it is only for generating, storing, and recalling waveforms. Surely someone offers a virtual instrument program for the SDG's.

Found the cause for phase error. At max allowed freq of 25MHz sine-square error is ~45° and it will scale eg absolute offset is ~5ns. Just in case checked at 500kHz also and indeed: 45° for sine-sine and 45.9° for sine-square.

Hey tautech,

Do you know if Siglent was ever able to get this this to trigger both channels at the same time with a software trigger?

I also purchased the SDG6000 series for my lab, and some guys have been pretty impressed by the value it offers.

Do you know if Siglent will be able to make these units capable of being triggered to do a burst/sweep? That would be super sweet.

Have you checked with the latest firmware ?
IIRC tech support said they would implement it but couldn't say when.
Not all changes/bugs are detailed in the changelog so I suggest you check with a unit......I haven't got one unpacked ATM.

I've just unpacked my SDG2042X after a few months of storage and while it powers up OK, none of the front panel buttons work!

The touchscreen still functions so I can turn the outputs on/off and the unit is clearly not frozen up, but I can't use the buttons or knob so can't adjust any parameters or get into the system menu etc. The light-up buttons all flash at startup and  the Parameter button is illuminated thereafter, so I think there's still a working connecting somehow, just the button inputs are being ignored.

Firmware 2.01.01.23R7.

Anyone have any ideas on how to recover it? It was working fine before I packed it up...

Humidity...   Let it warm up and/or place a lamp next to the buttons to speed up.

Thanks, I'll leave it on and keep trying. It's been stored indoors in a warm room though, so I wouldn't expect it to be too bad.

Hi There,

I was looking for this file (SDG2000_eevblog_23R7.zip) and seems that all previously posted links are broken.
Could you please upload it again?

I was trying to load ARBW data via visa (USB/Ethernet/GPIB) to my SDG2000 and got a bit stuck.
After asking Siglent support they sent me the attached demo script.

Nice support from them for my hacked device ;D

Is there any simple way that I can make a screen copy on internal or USB memory for my Siglent SDG2042X ? On my Siglent SDM3055 there is an option to do a screen copy to a USB stick but this is missing on the SDG2042X. My Rigol DS2102A and DP832A also support making screen copy to USB stick.

This was asked two years ago. I did not see a response from Siglent on this.  I was in the middle of harping on this when, on a lark, I grabbed my SDS screenshot code and put my SDG hostname in.  Well... see for yourself.

$ ~/sds_scdp.py -o test.png sdg2122x




I don't see this feature documented in the SDG programming guide.

The scopes have a similar SCDP command, its documented in the SDS2000 programming guide,
If you want help finding undocumented SCPI commands, send me the system application and I'll take a look. (don't own the device, but not hard to find in the file)

Hi,

maybe it has been reported earlier in this thread already but unfortunately I couldn´t find a ´search in this thread´ function.
What I like about my SDG2042X besides it beeing a great generator is that I can use it for curve tracing of small signal transistors  :-+
As it offers two channels one can easily and quickly generate the Ramp resp. Staircase waveforms required.
I think it should also be possible to test power devices too in that I take a dc-capable power amplifier to boost the Ramp signal to the required voltage and current levels.
A simple Dual output lab-supply could then power the amp.
The supply is also useful to evaluate the Ic over Vbe curves ... supplying a constant voltage to the transistor´s collector and feeding the basis with a ramp signal.
In any case my old Philips PM3267 draws beautiful curves in a smashin´ GreenLantern green  ;) .... the new SDS2104X-E DSO isn´t as good in that ... as probabely all DSOs.

regards
Calvin

Just for completeness, I checked and the same SCDP (screendump) script from above works for my SDM3065X and SSA3021X.  I have a Microsoft Natural keyboard with 5 programmable hotkeys on the top.  I have them now each mapped to grab screenshots of my SDS2204X, SDG2122X, SDM3065X and SSA3021X respectively.  Just need one more piece of kit to fill out all 5 buttons.  If Siglent's electronic load is anything to write home about, that may well be it.

Been pumping for info on the E-load but zip being offered and zip on the Chinese website.  :(

Nice job on the hot keys.  :-+

Jeulin never heard of that one .... though it´s only 50m to France from my place ... but the blue looks are certainly fine  ;)

Now that's the best "TEA" excuse I've heard in a long time... "I had to buy another meter, there was an unused programmable hotkey on my PC's keyboard" :D

If he replaces it for a gaming keyboard then he better do some house upgrading also.  ;D
