Hi,
I am still new to VNA measurements and started yesterday to do a calibration of my device.
I have the latest FW installed and I can understand some of the steps in calibration, but not all:
OPEN --> connect open header to CH0
SHORT --> connect storted header to CH0
LOAD --> connect 50 Ohmn terminator header to CH0
ISOLN --> what do I have to do here?
THRU --> my guess is I straight connect CH1 to CH0?
DONE --> finish!
Why do I have to do a RESET first? So that measurements are done without any previous calibration? Makes sense, I guess...
Am I correct that CAL should be performed using the same cables that will be used for measurement? Makes sense, because the length will/can determine phase shifts, right?
If these questions are too basic for this thread, I can ask them in a separate topic - I don't want to hijack this nice thread, but I thought that it does generally fit in here.
Thanks,
Vitor
