A VNA measures the "system," so you must calibrate to remove the effects of cables and adapters.

Some VNAs can tune their receivers to multiples of the source frequency to measure second and third harmonics generated by the amplifier. Basics of RF Amplifier Test with the Vector Net...

Testing an RF amplifier with a is the gold standard for characterizing gain, impedance matching, and stability. 1. Essential Setup & Safety A VNA measures the "system," so you must

If your amplifier has a DC bias on the RF lines, use DC blocks to prevent damaging the VNA’s bridge circuitry. High isolation is critical for stability to prevent

Measures how much signal leaks from the output back to the input. High isolation is critical for stability to prevent oscillations. 4. Advanced Performance Metrics Modern VNAs can also measure non-linear characteristics:

Similar to S11, this measures how well the output port is matched to the load.
