Fast Device Tune Measurement
Allows simultaneous calibration of a device’s transmitter output
power and receiver input level across level and frequency in a
single sweep (per frequency band). The device must operate in
a test mode, which forces it to transmit a predefined series of
power steps at various uplink frequencies, and also forces it to
simultaneously tune its receiver to perform measurements (such
as RSSI) of the test set’s signal at various downlink frequencies
and power levels.
