[:SOURce<hw>]:AM:SENSitivity?
The command queries the input sensitivity of the external modulation input in %/V. The
command is only effective if the external modulation source is selected (SOUR:AM:SOUR
EXT). The returned value depends on the modulation depth setting (SOUR:AM:DEPTh).
This value is assigned to the voltage value for full modulation of the input.
Return values:
<Sensitivity> float
Example:
AM:DEPT 50
sets a modulation depth of 50 %.
AM:SENS?
queries the input sensitivity at the external modulation input.
Response: 50
since the voltage value for full modulation is 1V, the resulting sen-
sitivity is precisely 50%/V.
Usage: Query only
SCPI confirmed
[:SOURce<hw>]:AM:SOURce <Source>
The command selects the modulation source for amplitude modulation.
Internal and external modulation source can be selected at the same time.
Parameters:
<Source> INTernal | EXTernal
INT
INT is the LF generator. The frequency of the internal modulation
signal can be set in the SOURce:LFOutput subsystem.
EXT
The external signal is input at the EXT MOD connector.
*RST: INTernal
Example:
AM:SOUR INT
selects the internal modulation source.
[:SOURce<hw>]:AM:STATe <State>
The command activates/deactivates amplitude modulation.
Activation of amplitude modulation deactivates ARB, I/Q modulation, digital modulation
and all digital standards.
Parameters:
<State> 0 | 1 | OFF | ON
Example:
AM:STAT ON
activates AM modulation.
Usage: SCPI confirmed
