<depth>::=<NR2>[<units>]
where:
<NR2> is the depth of modulating frequency.
<units>::=PCT
MINimum sets the modulation depth to minimum value.
MAXimum sets the modulation depth to maximum value.
<depth>
SOURce1:AM:DEPth MAXimum
sets the depth of modulating signal on CH 1 to the maximum value.
This command sets or queries the internal modulation frequency of AM
modulation for the specified channel. You can use this command only when
the internal modulation source is selected. You can set the internal modulation
frequency from 2 mHz to 50.00 kHz with resolution of 1 mHz.
You can select the source of modulating signal by using the
[SOURce[1]]:AM:SOURce [INTernal|EXTernal] command.
