AM:DEPT 50
sets a modulation depth of 50 %.
AM:SENS?
queries the input sensitivity at the EXT MOD input.
Response: 50
since the voltage value for full modulation is 1V, the resulting sen-
sitivity is precisely 50%/V.
Example:
Query only
SCPI conform
Usage:
[:SOURce<hw>]:AM:SOURce <Source>
The command selects the modulation source for amplitude modulation. INT is the LF
generator. The frequency of the internal modulation signal can be set in the
SOURce:LFOutput subsystem. The external signal is input at the EXT MOD connector.
Internal and external modulation source can be selected at the same time.

AM:SOUR INT
selects the internal modulation source.
Example:
SCPI conformUsage:
[:SOURce<hw>]:AM:STATe <State>
The command activates/deactivates amplitude modulation.
Activation of amplitude modulation deactivates BB-AM, ARB, I/Q modulation, digital
modulation and all digital standards.
Parameters:
0|1|OFF|ON<State>
AM:STAT ON
activates AM modulation.
