AM/FM/PM Analyzer (Option 509)

AM/FM/PM Analyzer (Option 509)
Note 
Introduction
This chapter presents information and procedures that are used to make measurements when using the optional AM / FM / PM Analyzer mode (Option 509).
The AM / FM / PM Analyzer provides display and analysis of the key characteristics of analog AM, FM, and PM modulated signals. The AM / FM / PM Analyzer provides four different displays:
1.
RF Spectrum shows the RF Spectrum graph, which is similar to Spectrum Analyzer mode with carrier power, carrier frequency, and occupied bandwidth measurements. To get to this view, select the Measurements menu and then press RF Spectrum. To change the occupied bandwidth measurement, press RF Spectrum again and make changes as desired.
2.
Audio Spectrum shows the demodulated audio spectrum along the with the following measurements: Rate, RMS, Pk-Pk/2, SINAD, THD, and Distortion/Total. To change X-axis values to 2 kHz, 5 kHz, 10 kHz, or 20 kHz, press Audio Spectrum again and change Span. When analyzing FM and PM, the reference Y‑axis value is also scalable.
3.
Audio Waveform displays the time-domain demodulated waveform along with Rate, RMS, Pk-Pk/2, SINAD, THD, and Distortion/Total measurements. The X‑axis value can be changed by pressing Audio Waveform and changing the Sweep Time. When analyzing FM and PM, the reference Y‑axis value is also scalable.
4.
Summary displays all of the above mentioned measurements from RF Spectrum as well as the demodulated signal.
