[:SOURce[<n>]][:MOD]:PSKey:INTernal:RATE
Syntax
[:SOURce[<n>]][:MOD]:PSKey:INTernal:RATE {<rate>|MINimum|MAXimum}
[:SOURce[<n>]][:MOD]:PSKey:INTernal:RATE? [MINimum|MAXimum]
Description
Sets the PSK modulation rate of the specified channel.
Queries the PSK modulation rate of the specified channel.
Parameter
Name Type Range Default
[<n>] Discrete 1|2 1
<frequency> Real 2 mHz to 1 MHz 100 Hz
Remarks

This command is only applicable to the internal modulation source
( [:SOURce[<n>]][:MOD]:PSKey:SOURce ). The PSK modulation rate refers to the rate at which the
output phase "shifts" between the carrier phase and the modulation phase
( [:SOURce[<n>]][:MOD]:PSKey:PHASe ).

When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
Return Format
The query returns the PSK modulation rate in scientific notation, with 7 effective digits. For example,
1.02 (the PSK modulation rate is 150 Hz).
Example
:SOUR1:PSK:INT:RATE 150 /*Sets the PSK modulation rate of CH1 to 150 Hz.*/
:SOUR1:PSK:INT:RATE? /*Queries the PSK modulation rate of CH1 and the query returns
1.02.*/
[:SOURce[<n>]][:MOD]:PSKey:PHASe
Syntax
[:SOURce[<n>]][:MOD]:PSKey:PHASe {<phase>|MINimum|MAXimum}
[:SOURce[<n>]][:MOD]:PSKey:PHASe? [MINimum|MAXimum]
Description
Sets the PSK modulation phase of the specified channel.
Queries the PSK modulation phase of the specified channel.
Parameter
Name Type Range Default
[<n>] Discrete 1|2 1
<phase> Real 0° to 360° 180°
Remarks

In PSK modulation, the signal generator shifts its output phase between two preset phases (the carrier
phase and modulation phase).

When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
Return Format
The query returns the PSK modulation phase in scientific notation, with 7 effective digits. For example,
9.01 (the PSK modulation phase is 90°).
