frequencies up to 1 GHz the Test Set is set to generate levels between −10 and 125
dBm (in 5 dB steps) at it's DUPLEX OUT connector. The level is measured with
the tuned RF level function of the measuring receiver. At each frequency the
measuring receiver connection is moved to the RF IN/OUT and the level measured
from -40 to −125 dBm. As the test proceeds you may be required to recalibrate the
measuring receiver.
To extend the measurement frequency to 2 GHz the second method uses a
microwave converter and amplifier to extend the measurement range (see
