Description
Sets or queries the modulation depth for internal
sources only. The default is 100%.
Note
The function generator will not output more than
±5V, regardless of the modulation depth.
The modulation depth of an external source is
controlled using the ±5V MOD input port on the
rear panel, and not the SOURce[1]:AM:DEPTh
command.
Syntax
SOURce[1]:AM:DEPTh {<depth in percent>
|MINimum|MAXimum}
Parameter
<depth in percent>

Sets the modulation depth to 50%.
Query Syntax
SOURce[1]:AM:DEPTh? [MINimum|MAXimum]
Return Parameter
<NR3>
Return the modulation depth as a
percentage.
Query Example
SOUR1:AM:DEPT?
