Hi Andrew,

thank you for the answer.

when i finished the calibration i didn’t save the relative file, so the S21 parameter was not set to 0. Saving the configuration file, the S21 parameter is set to 0.

I have another question:i have to measure a dut with a gain of about 70 dB. To be able to perform this measurement i need to insert a fixed 50 dB attenuator at the output of port 1. How can I include the presence of the attenuator in the calibration setup so that the S21 parameter that I am going to measure is exactly equal to 70 dB?

Thank you in advance,

Matteo
