PSK Rate

The PSK rate is the rate at which the output phase “shifts” between two preset phases. The range of the PSK rate is 2 mHz to 100 kHz. The default PSK rate value is 10 Hz.

Soft Front Panel Operation

On the PSK Rate panel as shown in Figure 2- 24, input the desired PSK rate value and select the unit from the drop down list.

PSKey:INTernal:RATE {<rate in Hz>}

PSK Deviation

The deviation setting represents the phase variation of the shifted waveform from the carrier waveform. The deviation can be set from 0 to 360 °. The default deviation setting is

180°.

Soft Front Panel Operation

On the Deviation panel as shown in Figure 2- 24, input the desired deviation value.
