SOURce[1|2]:SUM:AMPL
Source Specific
Command
Description
Sets or queries the amplitude of the modulating
waveform from the carrier waveform. The default
phase amplitude is 100%.
Note
If an external SUM source is selected, the
amplitude of the modulated waveform is
controlled using the ±5V MOD INPUT terminal on
the rear panel. A positive signal (>0~+5V) will
increase the AMPLitude (up to the set amplitude),
whilst a negative voltage will reduce the
amplitude.

Example
SOUR1:SUM:AMPLitude +3.0000E+01
Sets the amplitude to 30%.
Query Syntax
SOURce[1|2]:SUM:AMPLitude?
Return Parameter
<NR3>
Returns the amplitude .
