[: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.
Parameters:
<Source>
INT | EXT
INT
INT is the internal modulation source which is selected with com-
mand
AM:SOURce:INTernal
and configured in the
SOURce:LFOutput
subsystem.
EXT
The external signal is input at the MOD EXT connector.
*RST:
INTernal
Example:
AM:SOUR INT
selects the internal modulation source.
Usage:
SCPI confirmed
[:SOURce<hw>]:AM:STATe
<State>
The command activates/deactivates amplitude modulation.
Parameters:
<State>
0 | 1 | OFF | ON
Example:
AM:STAT ON
activates AM modulation.
Usage:
SCPI confirmed
SOURce Subsystem
