I keep wanting to get this machine.... then keep thinking won't use it enough.
Anyone give some clues or encouragement?!
It would be as expensive as anything else on the bench but will I start finding uses in proportion?
Yes those things - and in the most literal sense the decent Stereo Microscope - are literally the eyes with which one can see.... Was sort of hoping the the AWG could be a part of that in ways that might surprise one that doesn't have one.
16bit DAC and better navigation seem "must haves" and the price is not off putting.

Hello. Could anyone point me to someone on these forums who might now how to hack into this on a deeper level.
I don't want to unlock this device. I just want to program it so it can be remotely controlled to trigger both channels at the same time as well as sending out an AUX trigger.
I'm wondering if this is possible.

It's perfectly possible, but would likely require revision of the FPGA logic, and maybe sacrificing one unit in order to reverse-engineer the PCB. It would take quite a lot of time without having the original source files as most/all of the software would need to be rewritten (ASAIK disassembling a FPGA binary is generally not done). I don't have the available time or desire to do this, but could give you some pointers on how to proceed. I may even be able to XRay the analog PCB for you.
I'm not sure which aspect you can't achieve via standard setup of the SDG2042. Could you provide a bit more detail?
What would you want to use as the trigger input? There is a single AUX connector, which can either be the trigger input or an output. Or did you mean to trigger via the MTRIG SCPI command, which is equivalent to a manual trigger? If it is the latter, that should work without special trickery, I think (but have not tried).
Which leaves the "trigger both channels at the same time" part. I just had a quick look at my SDG2042X, and it seems possible to e.g. set up both channels in burst mode with a manual trigger, at the same time. Could you elaborate please? What do you want each channel to do, and could not convince the SDG to provide?
Finally, the trigger output you mentioned. Maybe that is where you run into a limitation? You should be able to get a sync output on the AUX jack, but with limitations (chapter 2.13.7 of the user manual). Again, could you please explain which signals you need on the main outputs, and on the AUX output?
The 1032X also can be 'improved' to 1062X model.
Edit: Try to trigger both channels at the same time with a manual trigger without using CH Copy Coupling. Not possible. Or attempt to program it.

I just gave this a quick try: Both channels in burst mode with manual trigger, no channel coupling. Selected different amplitudes, frequencies, cycle counts on the two channels. I can use the "trigger" softkey in either channel 1 or 2, and it will trigger a burst in both channels. I can also enable the "Trig Out" option for either channel 1 or 2, and it will provide a rising or falling edge trigger on the AUX output.
My hardware version is 02-02-00-35-00, and firmware 2.01.01.23R8.

Since I own an SDG1032X, I'm curious to know how I could do that. There may be the answer in this thread, but it is very hard to find it through more than a thousand replies.
Now I just need to be able to do burst and sweep at the same time without having to use a high pass filter.

You have piqued my curiosity there, and with your earlier mention of time-of-flight measurements. Would you mind describing what experiment you have in mind? Thanks!
Let's say you have some gas-like medium with a really high index of refraction with respect to an electromagnetic wave with a particular frequency propagating though this medium. Well, then it's fairly easy to map out the propagating electromagnetic field topology, and play it as a movie.
Why? 30MHz has a freespace wavelength of around 10meters. But in a medium with a high index of refraction, that wavelength can shrink down to centimeters as the speed of propagation is slowed down to some percentage of the speed of light.
Ah, thank you! And I assume the gas-ike medium, true to your user name and prior project, is a plasma?
I have no experience with that branch of physics at all. What dielectric constants, and hence wavelengths, do you obtain? If you get the wavelength down to centimeters, doesn't that still imply a rather sizeable plasma (for a homebuilt system?) if you want to obtain a meaningful spatial map of the propagation?
Back to the SDG2042X, what capability is missing which you need for your measurements? Are you looking for an envelope to modulate your burst amplitude, for a soft start and decay? (Maybe using a modulated continuous sine wave would work better?) Or you could store a modulated wavetrain, with the desired number of cycles, in AWG memory and play it just once?
.....As for my DS1054Z oscilloscope, I really wish there was a trigger channel that could be used so my sampling rate wouldn't halve when making this measurement.
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.
