Jon,
vsgSubmitTrigger and vsgSubmitIQ are part of the VSG60s streaming interface. If you call those functions it will push those actions into the queue to transmit ASAP. For example, if you wanted to transmit a single short waveform synchronized with a trigger, you would call in sequence
vsgSubmitTrigger
vsgSubmitIQ(yourWaveform)
vsgFlush/vsgFlushAndWait
The vsgOutputWaveform/vsgRepeatWaveform functions are just convenience functions that cannot be combined with others. vsgOutputWaveform transmits your waveform exactly once. It simply calls vsgSubmitIQ and vsgFlushAndWait for you. No triggering is possible with this function. vsgRepeatWaveform is simply a convenience over calling vsgSubmitIQ in a loop. It spins off a thread to do this for you and returns control to your application. If you perform any other action, the waveform being transmitted by vsgRepeatWaveform is interrupted.
If you want to re-transmit a waveform with thg trigger, you will need to recall the submitTrigger/IQ/flush sequence again.
I hope this helps.
Regards
