Set frequency of modulation wave

When modulation source is internal, frequency of modulation wave can be modulated.

After enabling DSBAM function, default of modulation wave frequency is 100Hz. Press

Param → ModFreq to change. Modulation frequency range: 2mHz~1MHz. When

modulation source is external, parameter list will hide the modulation wave option and

modulation frequency option, and carrier waveform will be modulated by an external

waveform. The range of modulation signal input from external is 0Hz~ 20Hz.

Comprehensive example

First make the instrument run in DSBAM mode, and then set an internal sine wave of

1kHz as modulation signal and a square wave with frequency of 2kHz, amplitude of 2Vpp.

The specific steps are as follows:

1)Use DSBAM function

Press Mod → Type → DSBAM (press soft key Type to select if Type is not highlighted).

2)Set carrier waveform parameters

Press Param → Type → Sine (if TYPE is not highlighted, press TYPE)
