Test Description
A calibrated power sensor is connected to the tracking generator output
to measure the power level at 50 MHz. The power meter is set for REL
mode so that future power level readings are in dB relative to the power
level at 50 MHz. The tracking generator is then stepped to several
frequencies throughout its range. The output power difference relative
to the power level at 50 MHz is measured at each frequency and
recorded.
