5.3 Optional Tests

The following tests are performed on units at the request of the customer, usually to verify specific customer requirements.

5.3.1 Noise Figure

Using a noise figure meter, the unit is tested to verify it operates within specification.

5.3.2 Group Delay

The testing software measures the linear, parabolic, and ripple components to verify the unit is within specification.

5.3.3 AM/PM

The testing software measures the slope of the amplifier’s insertion phase vs. output power.

5.3.4 Noise Power

Noise power is the total noise per bandwidth at the output of the unit when a signal is not present.

5.3.5 Harmonics

The testing software measures the 2nd and 3rd harmonics of the unit (as long as the frequency range is within the capabilities of the equipment).
