In this video I will be showing you how to use your nanoVNA in stand alone mode to measure the frequency response of a VHF receive preamplifier that exists in my amplifier add on.
Included in this video are
* Set up the nanoVNA for a frequency response (through) measurement on an active device
* Proper VNA calibration
* Make the measurement results more readable by changing the REFERENCE POSITION and SCALE.
See below for the time markers ...
