I tried to use Matlab to trigger the VNA(E5071C), but I find that i cannot trigger twice sequentially, here are the codes.

 

query(vna_obj,'TRIG:IMM;*OPC?')
query(vna_obj,'TRIG:IMM;*OPC?')

 

that makes no sense. 

 

 

Then I ask a friend to run the trigger twice on FieldFox N9917A, it works very well. Here are the codes,

 

query(vna_obj,'INIT;*OPC?');

query(vna_obj,'INIT;*OPC?');

 

 

What happens to my E5071C
