Using Waterfall and Spectrogram Displays (Opt. AYB)

To create a test signal

This procedure creates the test signal used throughout this chapter to
demonstrate waterfall and spectrogram features.

channel 1 input, and then overrange the analyzer to simulate a spectral
display with multiple tones.

Set the range to -30 dBm to overload the analyzer's ADC.
Press [Range] – 30 dBm.
After completing this step, the analyzer displays OV1 to inform you that
the signal is overloading the analyzer's ADC (in this case, the range is too
low). We do this intentionally to simulate a signal with multiple tones.
