5182A MXG Triggers

Question asked by n79c on Apr 27, 2011

I am programmatically (using scpi) setting a sweep list in the signal generator, and want to trigger it to step externally, all of which seems to work.  However, the 5182A seems to immediately start at the first frequency in the list...meaning that when the first (external) trigger occurs it moves on to the second frequency.  This does not seem correct, is there some way of either changing where in the list to start (i.e. do I need to set the start position to the last entry in the list), or make the first trigger actually initiate the first frequency? (I have used older 8645A which does this properly...this was suppose to be a replacement unit).

Basically the setup is just the following commands
The frequency, power, and dwell lists are loaded first then...

Frequency list F1 F2 F3 F4
It should start outputing the F1 when the first external trigger occurs, then move on to the F2 at the second trigger and so on.  After F4 is output the next trigger should start F1 again.

Any help would be greatly appreciated.
