1.5. To Set Modulate/Sweep/Burst

As shown in Figure 1- 13, there are three buttons on the front panel, which are

used for modulation, sweep and burst settings. The instructions below will help

you familiarize with the setting of these functions.

Figure 1- 13 Modulate/Sweep/Burst Button

1. Press Mod button, the modulated waveforms will be generated. The

modulated waveform can be changed by modifying the parameters such as

type, internal/external modulation, depth, frequency, waveform, etc.

SFG-20X Series can modulate waveform using AM, FM, PM, ASK, FSK,

PWM and DSB-AM. Sine, square, ramp and arbitrary waveforms can be

modulated (pulse, noise and DC cannot be modulated).
