2.3.3.4 Simulation modulation
The instrument supports basic simulation modulation including amplitude modulation (AM),
frequency modulation (FM) and phase modulation (PM). The instrument also allows pulse modulation
to be enabled by using internal or external signal through digital and analog switches. Pressing the

keys on the front panel or clicking [Amplitude Modulation],
[Frequency Modulation], [Phase Modulation] in the [Simulation Modulation] function area and the
[Pulse] function area on the screen will display the pop-up Amplitude Modulation, Frequency
Modulation, Phase Modulation and Simulation Modulation dialogs, respectively, as shown in
Fig.2.32, 2.33, 2.34 and 2.35. The instrument provides standard internal waveforms including sinc,
dualsinc, sweepsinc, triangle, zigzag, square and noise. Settings in Pulse Modulation Configuration
