4.1 Measurement of Continuous-wave
Signal
One of the most common tasks of spectrum analyzer is to
measure frequency and amplitude of signal. In the following
example, continuous-wave signal (300MHz, -10dBm)
generated by signal generator (Agilent E4421B) as signal to
be measured.
Operation steps:
1. Connect equipment
Connect signal output of signal generator with RF input of
UTS1000 Spectrum Analyzer.
