Hi,
Why does the phase measurement is negative?
I mean - I cal the VNA with thru and measure 0 deg. Now I add (lambda/4) length cable and measure -90 deg ?
Why the measured value is negative the logic says the measure should be +90 deg.
I'm sorry if it sound like a silly question but I ask few "experts" and they said that the way the VNA works. WHY ???
Thanks,
