PSK Rate Setting

When modulation source is internal, the moving frequency between carrier wave phase

and modulation phase can be set. After enabling PSK function, PSK rate can be set and

the settable range is 2mHz to 1MHz, the default rate is 100Hz. If need to change, press

Param → Rate in turn.

Modulation Phase Setting

Modulation phase indicates the change between the phases of PSK modulated waveform

and the phase of carrier wave phase. Settable range of PSK phase is from 0˚ to 360˚, and

the default value is 180˚. If need to change, press Param → Phase in turn.

Comprehensive Example

Make the instrument work in phase shift keying (PSK) mode, then set a sine wave with

2kHz and 2Vpp from the internal of the instrument as a carrier wave signal, finally, make

carrier wave phase and modulation phase move between each other with 1kHz frequency.

Specific steps are seen as following:

Enable Phase Shift Keying (PSK) Function

Press Menu → Mod → Type → PSK in turn to start the PSK function.

Set Carrier Wave Signal Parameter

Press Carrier → Type → Sine in turn to select sine wave as carrier wave signal.
