The Tracking Generator operates over a frequency range of 100 kHz to 7.l GHz, and provides a signal with an output frequency that is the same as the tuning frequency of the MS2721B spectrum analyzer. The output power and level accuracy are specified from 450 kHz to 7.1 GHz. When the spectrum analyzer is set to zero span, the output is a CW signal. The output power is leveled and can be adjusted from 0 dBm to – 40 dBm in 0.1 dB steps.
