Synchronizing VNA with Controller During E-Cal

Hi All,

I'm working on remotely issuing the SCPI commands to perform an E-Cal on an E5071C running firmware A.11.31. I'm communicating via GPIB(talker listener) or USB.

The problem I'm having is I can't seem to get my controller to synchronize with the ENA. The solution I use for triggering the Instrument doesn't seem to work with the E-Cal procedure. No matter what command I issue to the instrument it doesn't respond until the E-Cal is finished. When I trigger the Instrument I check the Status register to know when it's done, but I can't do that with the E-Cal because I won't receive a response.

My goal is to find a non-blocking solution. I understand that I could use a SRQ, but before I Implement this solution I want to make sure I haven't missed something in the documentation that would explain this behaviour. For reference I issue this command to perform the E-Cal: "SENS:CORR:COLL:ECAL:SOLT4 1,3,2,4".
