I am trying to read a trace from a PNA-X as quickly as possible with the following:

I turn off continuous sweep with:
INITiate1:CONTinuous OFF;

To trigger a sweep I am using:

But it takes about 7 seconds for that operation to complete and I hear clicking inside that analyzer like an attenuator is being switched. When I push the Single button on the PNA front panel the sweep completes in only about 47mS.

Anyone know how I can speed this up?
