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.
Maximum Maximum
Flatness ≤ 10 MHz −3.5 dBm +3.5 dBm
Flatness > 10 MHz −2.5 dBm −2.5 dBm
