Hello,
I have been using Matlab instrument control toolbox to talk to my N5221B PNA and everything worked perfectly until a recent system reboot. After the system reboot, when I send the read data command CALC:DATA:SNP:PORTs?, it tooks almost two minutes to return the results of a 4-port measurement (I checked the SCPI monitor after I sent in the command). The following command in my script is a bin block read. If I don't wait long enough, it surely leads to an error. I haven't changed any measurement settings, the sweep range and data points keep the same. I am wondering what could be the possible reason causing this extreme delay in returning the measurement data. Any advice will be appreciated. Thanks
Can you capture an IO Monitor log of the transaction, and then share it with us?
What is the VISA connection string? (are you using GPIB, VXI-11, HiSLIP, sockets?)
