#317: NanoVNA Port Extension using the Electrical Delay setting

The user calibration, described in video #313 (https://youtu.be/x-tbvAbh9jk), establishes a calibration or reference plane for the complex reflection/impedance measurement on the VNA. If you need to use adapters, fixtures, cables, etc. to connect to you DUT, you may need to apply a port extension to move the calibration plane to the DUT end of these "additions". This video discusses what a port extension is, why you might need it, and how to do it on the NanoVNA.
