<frequency>
2 mHz~ 20 kHz
SOUR1:SUM:INT:FREQ MAX
Sets the frequency to the maximum value.
SOURce[1|2]:SUM:INTernal:FREQuency?
<NR3>
Returns the frequency in
Hz.
SOUR1:SUM:INT:FREQ? MAX
+2.0000E+04
Returns the modulating frequency (20kHz).
SOURce[1|2]:SUM:AMPL
Source Specific
Command
Sets or queries the amplitude of the modulating
waveform from the carrier waveform. The default
phase amplitude is 50%.
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.
SOURce[1|2]:SUM:AMPL{< percent>|minimum
|maximum}
<percent>
0%~100%
SOUR1:SUM:AMPLitude +3.0000E+01
Sets the amplitude to 30%.
SOURce[1|2]:SUM:AMPLitude?
<NR3>
Returns the amplitude .
SOUR1:SUM:AMPLitude?
+3.0000E+01
The current amplitude is 30%.
