You can downgrade to hackable version 17R5, do the hack, and upgrade to 22R5.
No, the firmware update does not affect the hack.
I am finding one thing a bit irritating but maybe I am missing something. It seems like the only way to set the amplitude units is to start to enter the value via the numeric keys. This causes the buttons below the display to allow the user to select the amplitude units. Once I have set an amplitude I would like to be able to change the units without changing the actual amplitude, eg V RMS to V Pk to Pk or dBm to mV RMS. There doesn't appear to be a way to do this without entering a new value.

You're right, one has to type a number and then the unit, and I'd find somewhat scary If one could inadvertently change lets say 10 mVpp into 10Vpp with one keystroke, a switch from 10dBm to 10Vpp could be ruin instantly some RF circuits
You can, however easily change the first, second, third.... digit of a number with a quick turn of the knob.
I have just got my SDG2042X and I am really liking it.

If it isn't currently possible could I suggest Siglent consider adding this feature. For example, holding the Amplitude button down could cause the Units menu to appear, permitting the user to change the units.

Others that think this is a worthwhile addition ?
That’s exactly how any modern instrument should behave, with the only difference, that the unit-keys would not be visible all the time due to the soft menu architecture. Consequently, there has to be a key to display the units menu, and it sounds perfectly plausible to use the “Amplitude” key for that.
Tautech: Yes using the latest software version.
Interesting responses. TBH I am a hobbyist so I don't have professional experience of modern test equipment UIs.
I guess I was just thinking of the SDG2042X performing a unit conversion for me, eg V pk-pk to RMS and dBm to mV RMS. Changing from V pk-pk to mV pk-pk would not make sense in that context. I certainly wasn't expecting the output level to change.
This is a great thread BTW, I learnt a lot about the SDG2042X by reading it ...
Thanks,
Andrew
Tautech,
Do you know if the next firmware update will allow for a software trigger to be able to trigger both channels at the same time? Are they working on that for the next update? If so, do you know when that update will take place?

Can't you do that with Ch Copy/Track, then use Burst on the Tracked Ch with the start set to Ext and initiate it from an Aux In signal or use the Manual Burst start ?
All that's in FW 22R5.....now I haven't tried it as I've just got new stock today and had to fire one up to check how it might be done in the UI.
Your turn. Tell us if that works.
Ah, do you mean a SCPI command ?
Not at all conversant with them, sorry. But if the commands mentioned above are available maybe you can try that procedure ?
The last update was last October so unless something else is a problem I don't know of any updates coming soon.
I think the factory is quite busy working on some other new goodies for y'all.

Yes, with a SCPI command. Would make the unit super awesome if it could do that. That's really the only goodie I need.
Thank you so much. I really appreciate it.
I wonder how Chinese new year will effect the progress on this. I know some of the manufactures in Taiwan are going to be completely shut down over the course of a week.
Super awesome if they are able to get this to work.
If this unit can trigger bother CH.1 and CH.2 outputs from a SCPI command.... AND.....have a DC pulse with a set width come out of the output on the back....Nothing even holds a candle to this within this frequency range (IMO). And the guys in Ohio who came out to my lab, if they can demonstrate this functionality, it would be a huge selling point.
Also, if the salesmen in Ohio had a labtop they could hook up to this sig-gen with an awesome LabVIEW VI and/or MatLAB interface to demonstate this, I think it would catch potential buyer's attention even moreso.....is siglent Ohio hiring? I feel like I could sell these things to those who are program savvy and could realize the value this sig gen brings. I think its incredible, and with another firmware update, would bring shame upon anything else in the market within this range of frequency.

Set the parameters and then OUTP to OFF, then *WAI (wait) followed by OUTP 's to ON
Is this a valid "workaround" solution ?
Is the VKEY command also of use to trigger both outputs ?
Commands from the Siglent SCPI manual:

The attached picture shows in theory what I'd like to do with SDG2042X, I'm not sure if I did this with the most recent update. Here we can see two different signals with two different frequencies offset with some time difference from the start of the burst.
Also, I would be using the Aux/out as a pulse delay generator, (the purple line) with some set width and some set delay(+/-) relative to ch.1 or ch.2.
It looks like this machine could do that with the correct firmware, that is.
Aux Out - Burst mode - Set width, set amplitude, set delay relative to ch.1 - trigger from the same SCPI and/or manual as ch.1
