I have following questions on the ZES utility. We are using signal generator and feeding the receiver input Rx1 with LTE DL waveform. I was feeding burst signal to the receiver input.


  1. Is there way to capture the IQ when the signal is present, How we can capture the IQ data when the signal is transmitted. I believe we should use the trigger, Can you please let us know the suitable option of the trigger used for the capture and measuring EVM test. 
  2. How to use the TDD_SM_Pulse in the test?
  3. Are you using the VSA data and importing to Agilent spectrum analyzer and measure the EVM. We have the LTE module support in our spectrum analyzer but i could not find the option to import the vsa file. please share if you have more details on that.
