Title says it all pretty much. It works in the “standard” waveform generator, which btw has also an option for internal triggering source, which would be a welcome feature on the AWG instr. as well.
Hi @mschuette,
I’m not able to reproduce this issue, are you able to share more information or screenshots of your setup?
To get the AWG to use the external trigger in burst mode I connected Output 1 of “Moku-000965” to the External trigger of “Devvy 96” and then connected Output 1 of “Devvy 96” to Input 1 of “Moku-000965” to view the signal in the Oscilloscope. The signal connected to the External trigger was a 1 Hz, 1 Vpp square wave with an offset of 500.0 mV to ensure it exceeded the 700 mV trigger threshold of the Ext. trigger. I’ve attached screenshots of this setup for you.
I hope this helps and please share more information about your setup if this does not help,
Indira
Dear Indira,
I’m using a 10Hz, 0-5V TTL trigger on the external input. I tested everything from 1us to 50% duty cycle. I think the 700mV trigger threshold does not apply to the external trigger, it is just the setting when using Inputs 1-4 for triggering and becomes inactive when the ext. trigger is selected. But since the trigger works on the standard waveform generator, I think this is not the problem.
Please try generating bursts of 4096 exponential decay pulses at 4.5MHz rep rate and 1.2Gsa/s with 256 manual points and 355° phase. Try doing this for output 1 and 2 simultaneously.
