[: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.

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,
1.500000E+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
1.500000E+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.

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,
9.000000E+01 (the PSK modulation phase is 90°).
