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.

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°).
Example
:SOUR1:PSK:PHAS 90 /*Sets the PSK modulation phase of CH1 to 90°.*/
:SOUR1:PSK:PHAS? /*Queries the PSK modulation phase of CH1 and the query returns
9.000000E+01.*/
[:SOURce[<n>]][:MOD]:PSKey:POLarity
Syntax
[:SOURce[<n>]][:MOD]:PSKey:POLarity {POSitive|NEGative}
[:SOURce[<n>]][:MOD]:PSKey:POLarity?
Description
Sets the PSK modulation polarity of the specified channel to Positive (POSitive) or Negative (NEGative).
Queries the PSK modulation polarity of the specified channel.

Remarks
 When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
 In the internal modulation (
[:SOURce[<n>]][:MOD]:PSKey:SOURce), set the polarity to "Positive",
and the generator will output the carrier phase when the modulating waveform amplitude is a logic low
level. It will output the modulating phase (
[:SOURce[<n>]][:MOD]:PSKey:PHASe) when the
modulating waveform amplitude is a logic high level. The situation is the opposite when the polarity is
