SDG2042X - Triggering both channels at the same time in burst mode?
Plasmateur:
--- Quote from: edit ---Functionality I need,
CH.1 to burst with X delay @ Y frequency with Z cycles/Burst period
CH.2 to burst with A delay @ B frequency with C cycles/Burst period
Both channels must trigger from the same external/manual trigger
--- End quote ---
--- Quote from: Update ---
Using the internal trigger it is possible to get very close to doing what I need this machine to do, however it is not optimal for my application as I need to be able to trigger both channels from external/manual.
For now, here's how to do it.
Set all the parameters as stated above in the edit quote - CH.1(A,B,C) & CH.2(X,Y,Z)
Set burst period to something long, say several seconds. Both channels will trigger after some parameter is changed. If using 10Vpp on a particular channel, change it to 9.90Vpp and the unit will trigger. Alternatively this can be done by changing the frequency as well.
I also spoke with someone at Siglent, and they said they were working on it. They even asked if I was from eeVBlog....wow. Awesome!

I've looked at the manual for this signal generator and can't seem to find how it is possible to trigger CH.1 & CH.2 at the same time. I set both channels to manual, however only the select channel will burst when hitting the trigger button. What's most important is that I am able to trigger both of these channels at the same time from an external trigger, however I can only select one channel to be externally triggered.
Is there some sort of software update which allows this functionality or am I missing something?
I would also like to be able to eventually send a software trigger through LabVIEW to be able to trigger both of these channels at the same time.

2.13 To Set Utility Function
CH Copy Coupling: Set the track, channel coupling or channel copy function.
So Channel coupling (copy) with Ext trigger should work, does it not?
Plasmateur:
Yes, and thank you, however I should have been more clear.
I was able to get both channels to output at the same time from the manual trigger by using the channel track function, however I want to be able to pulse two different frequencies on separate channels at the same time. Using the track function I was unable to do this.

Another quick look at the manual and we see
2.11 To Set Burst Function
External Gated output.
P 74
Have a try with that.
Plasmateur:
I starting playing around with the suggestion and I'm not sure if gating is going to meet my requirements. By sending a gated pulse to the external trigger, both channels will burst at the same time for the same length of time. What I need is the following,
CH.1 to burst with X delay @ Y frequency with Z cycles/Burst period
CH.2 to burst with A delay @ B frequency with C cycles/Burst period
It would be nice if could simply set up the parameters for each channel and trigger them off the event of rising edge or a manual trigger. Possibly a software trigger could do this or this could be programmed through SCIP commands?
