Remote command:
[:SOURce]:LFOutput<ch>:FREQuency
on page 349
LF Gen Shape
Selects the waveform shape of the LF signal.
Note: The installed hardware determines the available settings. Use the Hardware
Config dialog to check the hardware the instrument is equipped with.
For information on the required hardware revision, refer to the release notes.
Remote command:
[:SOURce]:LFOutput:SHAPe
on page 357
AM Sensitivity
Displays the input sensitivity of the externally applied modulation signal at the MOD
EXT input in %/V in
AM Type Linear mode, and dB/V in AM Type Exponential mode.
The modulation depth entered under AM Depth is achieved with 1 Volt modulation of
the input.
Remote command:
[:SOURce<hw>]:AM:SENSitivity?
on page 327
AM External Coupling
Selects the coupling mode (AC or DC) for external feed.
Note: Coupling for external feed via input MOD EXT can be set independently for all
modulations using the external modulation signal.
"AC" Disconnects the DC voltage component and uses only the AC com-
ponent of the modulation signal.
"DC" Uses the modulation signal with both components, AC and DC.
Remote command:
[:SOURce<hw>]:AM:EXTernal:COUPling
on page 326
Ext. Impedance
(Source "External" only)
Sets the impedance for the external modulation signal, applied at the MOD EXT con-
nector.
You can select 600 Ohm or high (>100 kOhm).
This setting affects all analog modulations which use the external modulation signal.
