Siglent SAG1021I AWG questions

[ninevoltz]

I've got an SAG1021I waveform generator I use with my SDS1204X-E, and I have a couple of questions. First, what does the AUX jack do? There is no manual for this thing anywhere. Second, how do you load waveforms onto it with EasyWaveX? I've installed all of the VISA/IVI drivers, and it appears in NI-MAX when I plug it into my PC, but EasyWaveX refuses to connect to it. What could I be doing wrong here? Siglent would not answer my request for support.

I've got an SAG1021I waveform generator I use with my SDS1204X-E, and I have a couple of questions.

Got one out especially.

First, what does the AUX jack do?

Provides an I/O to sync other devices with.
Connect a BNC to a spare channel and observe its behavior when you output waveforms.

There is no manual for this thing anywhere.

Most of what you need is in the SDS1004X-E datasheet and manual starting from P186.
https://int.siglent.com/u_file/document/SDS1000X_E_SDS1000X_U_UserManual_EN.pdf

Second, how do you load waveforms onto it with EasyWaveX?

Described in the section: Stored Arb on P188

I've installed all of the VISA/IVI drivers, and it appears in NI-MAX when I plug it into my PC, but EasyWaveX refuses to connect to it. What could I be doing wrong here?

EasyWaveX is a Windows utility and configured for direct connection to standalone AWG or to your DSO to which you send a Stored Arb as mentioned above.

Some crashing around in the DSO's SAG1021I menu, screenshots attached.

Thanks for the reply! I'll try it out next time I fire up my scope.

Few questions on SAG1021I
1) Are there firmware updates for this module? Couldn't find any resources online.
2) Label on SAG1021I says "50MHz 125MSa/s". SDS800X HD wavegen & bode plot seems to limit max freq to 25MHz (SDS800X HD manual also mentions 25MHz). Is 25MHz max frequency limit in combination with SDS800X HD?

1. Yes.
Dependant on the DSO series you need use it with.

2. Yes however some Siglent DSO's support SAG1021I use to 50 MHz, eg SDS3000X HD models.

Thanks for reply. Currently wavegen works great, haven't noticed any bugs.

BTW, I noticed that output of SAG1021I is galvanically isolated (only up to 42V), that is useful in some situations.

Yes the later SAG1021 was upgraded to an I version which provides output isolation, thereby making the earlier SAG1021 obsolete.

SAG1021 Question,

is there a possibility to load a self created step function inside the SAG
in order to measure semi. cond. characteristic curve.

The build in step function provides seven steps.

I would like to increase this pattern to a decimal number like 10, 20, ...

Thanks for any usefully hint concerning this issue.

Seems that I need EasyWaveX for this purpose.

Unfortunately I run Linux and I had so far not been able to install it
on wine due to the lake of visa32.dll.

Any hint how to obtain this lib without installing the NS VISA package.

On the other hand I found awglib.dll in the EasyWaveX package.

>binwalk awglib.dll

Perhaps the proper commands are found inside this lib to
program the SAG device.


Any hints would by appreciated if someone had already found a solution.

Thanks in advance
Markus
