nanoVNA: Measuring the Frequency Response of an Amplifier Filter (068e)

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.
