Just in case Easywave was causing issues there, you could double check by creating the two-tone wave in another way.
I wrote a simple script for GNU Octave to create arb waves in Siglent CSV format. The included example is a two tone sine.

You got the quote attribution mixed up, it was plasmateur who ran into problems with the Easywave-generated waveform. But I second your recommendation to use a different tool to generate the samples. I have not become friends with EasyWave, and have simply used Excel to generate wave samples and export them as CSV.

Oops, fixed, thanks.

For the burst and sweep mode you can set each channel up to use the external trigger, now I don't own that model to test that it works, but by using an external AUX trigger you may be able to accomplish what your trying to do
You tee off that aux trigger to the scope and I think that would meet your requirements.

I should point out you can use this to both burst and sweep arbitary waveforms,

It also appears as there is no SCPI command that can be used to capture the screen display which could also be used to snapshot the data.

Anyone had any luck capturing this data via SCPI? Failing that there is always the cell phone camera :-DD

The SDG2000X uses the same screen dump command as all Siglent gear.  I have screen dumps via SCPI from SDS, SDG, SDM and SSA devices.

Just point it at your AWG and give it a shot.

Problem is that you cannot burst and sweep at the same time. He needs to go from no signal to sweep to zero signal.

Also, when I attempted to generate a two frequency sinusoid with the Easywave, the intermod products, or the sidebands that I observed on a spectrum analyzer appeared to much much higher than when just combining two channels.

Just in case Easywave was causing issues there, you could double check by creating the two-tone wave in another way.

I'll give your code a shot.

I also tried to generate a CSV with Matlab, and found the sidebands to be higher than just combining two channels.

I'll probably end up running your code and finding out I was bad at generating a CSV. Thanks!

Anyone having problems with the PowerOn Last feature?

Supposed to startup up with last used settings.  Sometimes does, usually not and many times comes up with defective waveforms as attached, that can only be fixed by toggling Utility/Mode/Phase Locked and Independent.

Settings that don't seem to be saved are random, frequency, phase lock, waveform ect.  The defective waveforms don't seem to correspond with what's in channel 2.

ver 2.01.01.23R8
hw 02-02-00-35-00

Here's a 40Mz sine wave:
