RF vs. Time Waveforms

The underlying I&Q data that’s used to create the spectrums shown by Spectrum View can also be used to calculate RF vs. Time waveforms that show how various characteristics of the RF waveform vary over the entire acquisition, not just where Spectrum Time is positioned. Three types of waveforms are
available:

• Magnitude – The instantaneous magnitude of the spectrum vs. time
• Frequency – The instantaneous frequency of the spectrum relative to the center frequency vs. time
• Phase – The instantaneous phase of the spectrum relative to the center frequency vs. time

Each of these traces can be turned on and off independently, and all three can be displayed simultaneously.
These waveforms are shown in Figures 10-12 below and reveal additional information about the signal of interest. There are four time-domain waveforms shown in the Waveform View in each of the images. The top one is the analog view of the signal. Next is the RF Magnitude vs. Time waveform, then the RF Frequency vs. Time waveform and finally the RF Phase vs. Time waveform.
