waveform.
 When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
 If the sweep function (
[:SOURce[<n>]]:SWEep:STATe) or burst function
(
[:SOURce[<n>]]:BURSt[:STATe]) is currently enabled, it will be disabled automatically when the
modulation function is enabled.
 If the harmonic function is currently enabled (
[:SOURce[<n>]]:HARMonic[:STATe]), the modulation
function cannot be enabled (i.g. the harmonic cannot be modulated).
Return Format
The query returns ON or OFF.
Example
:SOUR1:PM:STAT ON /*Enables the PM modulation function of CH1.*/
:SOUR1:PM:STAT? /*Queries the on/off status of the PM modulation function of CH1 and the query
returns ON.*/

[: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.

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).
