8-13. SUM Modulation (SUM) Commands
8-13-1. SUM Overview
The following is an overview of the steps required to generate a SUM modulated
waveform.
Enable SUM
Modulation
Configure Carrier
Select Modulation

Select Shape
Select Modulating
Frequency
Set AMPL
1.
Turn on SUM modulation using the SOURce[1|2]:
SUM: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]:SUM:SOUR command.
4.
Use the SOURce[1|2]: SUM: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]:SUM:INT:FREQ command. For internal
sources only.
6.
Use the SOURce[1|2]:SUM:AMPL command to set the
modulating amplitude.

Set
Query
Description Turns SUM Modulation on or off. By default SUM modulation
is off.
Note Burst or sweep mode will be disabled if SUM modulation is
enabled. As only one modulation is allowed at any one time,
other modulation modes will be disabled when SUM
modulation is enabled.
Syntax SOURce[1|2]:SUM:STATe {OFF|ON}
Example SOUR1:SUM:STAT ON
Enables SUM modulation
