Re: Which Type of Jig?

 

I have understood that calibration with a jig in place moves the reference plane of the device to the ¡°business end¡± of the jig, so that it will be accurate despite the stray reactances of the jig. Is this not the case?

In my opinion all of the jigs shown in this thread significantly degrade the true potential of the nanovna. They are fine if you just want to roughly measure reactance across LF through to VHF but they will significantly degrade the performance of the nanovna for critical measurements like component ESR.
