 [:SOURce[<n>]][:MOD]:PM[:DEViation]
 [:SOURce[<n>]][:MOD]:PM:INTernal:FREQuency

[:SOURce[<n>]][:MOD]:PM[:DEViation]
Syntax
[:SOURce[<n>]][:MOD]:PM[:DEViation] {<deviation>|MINimum|MAXimum}
[:SOURce[<n>]][:MOD]:PM[:DEViation]? [MINimum|MAXimum]
Description
Sets the PM phase deviation of the specified channel.
Queries the PM phase deviation of the specified channel.
Parameter
Name
Type
Range
Default
[<n>]
Discrete
1|2
1
<deviation>
Real
0° to 360°
90°
Remarks
 When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
 Phase deviation indicates the deviation of the modulating waveform phase from the carrier waveform
phase.
 When the external modulation source (
[:SOURce[<n>]][:MOD]:PM:SOURce) is selected, the phase
deviation is controlled by the ±5 V signal level on the rear-panel [Sync/Ext Mod/Trig/FSK]
connector. For example, if the phase deviation is set to 180°, +5 V signal level corresponds to a 180º
phase variation. The lower external signal levels produce less deviation.
Return Format
The query returns the PM phase deviation in scientific notation, with 7 effective digits. For example,
5.000000E+01 (the PM phase deviation is 50°).
Example
:SOUR1:PM 50 /*Sets the PM phase deviation of CH1 to 50°.*/
:SOUR1:PM? /*Queries the PM phase deviation of CH1 and the query returns 5.000000E+01.*/
[:SOURce[<n>]][:MOD]:PM:INTernal:FREQuency
Syntax
[:SOURce[<n>]][:MOD]:PM:INTernal:FREQuency {<frequency>|MINimum|MAXimum}
[:SOURce[<n>]][:MOD]:PM:INTernal:FREQuency? [MINimum|MAXimum]
Description
Sets the PM modulation frequency of the specified channel.
Queries the PM modulation frequency of the specified channel.
