8-12. Phase Modulation (PM)Commands
8-12-1. PM Overview
The following is an overview of the steps required to generate a PM modulated
waveform.
Enable PM
Modulation
Configure Carrier
Select Modulation
Source
Select Shape
Select Modulating
Frequency
Set DEViation
1.
Turn on PM modulation using the SOURce[1|2]:
PM:STATe ON command.
2.
Use the APPLy command to select a carrier waveform.
Alternatively, the FUNC, FREQ, AMPl, and DCOffs
commands can be used to create a carrier waveform with
a designated frequency, amplitude and offset.
3.
Select an internal or external modulation source using the
SOURce[1|2]:PM:SOUR command.
4.
Use the SOURce[1|2]: PM:INT:FUNC command to select
a sine, square, upramp, dnramp or triangle modulating
waveshape. For internal sources only.
5.
Set the modulating frequency using the
SOURce[1|2]:PM:INT:FREQ command. For internal
sources only.
6.
Use the SOURce[1|2]:PM:DEV command to set the phase
DEViation.
8-12-2. SOURce[1|2]:PM:STATe
Set
Query
Description
Turns PM Modulation on or off. By default PM modulation is
off.
Note
Burst or sweep mode will be disabled if PM modulation is
enabled. As only one modulation is allowed at any one time,
other modulation modes will be disabled when PM
modulation is enabled.
Syntax
SOURce[1|2]:PM:STATe {OFF|ON}
Example
SOUR1:PM:STAT ON
Enables PM modulation
