My question is it necessary to have the Nanovna set to the
frequency to be tested and calibrated before connecting to the computer and Saver
software?
Hi
I asked myself the same question as you. Obviously not: it is not necessary to calibrate the box before. You do with Calibration from nanovna-saver. I'm not smart enough to have known how to use the "normal" calibration so I do with the wizard.
I assume that you have understood correctly that the short-circuit, open and load operations are to be carried out flush with the equipment to be tested; for example at the end of the aerial cable (by disconnecting the aerial). Without putting too much sweep in frequency, provides wide and with many segments (each of 101 bars). Note in the file name the frequency band and where you did the calibration. Nanovna-saver says nothing if later, your measurement band is not in the band used during the calibration. Obviously the measurements are then tainted with large errors.
It is possible, with Excel, to correct the calibration file to smooth out the false (noisy) measurements.
