REMOTE INTERFACE
235
Example SOUR1:PM:INT:FREQ MAX
Sets the frequency to the maximum value.
Query Syntax SOURce[1|2]:PM:INTernal:FREQuency?
Return Parameter Returns the frequency in
Hz.
Example SOUR1:PM:INT:FREQ? MAX
+2.0000E+04
Returns the modulating frequency. (20kHz)
SOURce[1|2]:PM:DEViation
Source Specific
Command
Description Sets or queries the phase deviation of the
modulating waveform from the carrier waveform.
The default phase deviation is 180°.
Note For external sources, the phase deviation is
controlled by the ±5V MOD Input terminal on the
rear panel. If the phase deviation is set to 180
degrees, then +5V represents a deviation of 180
degrees. A lower input voltage will decrease the
set phase deviation.
Syntax SOURce[1|2]:PM:DEViation {< phase>|minimum
|maximum}
Parameter 0°~360°
Example SOUR1:PM:DEViation +3.0000E+01
Sets the deviation to 30°.
Query Syntax SOURce[1|2]:PM:DEViation?
Return Parameter Returns the deviation .
Example SOUR1:PM:DEViation?
+3.0000E+01
The current deviation is 30°.
