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 766
ɸM Sensitivity
Displays the input sensitivity of the externally applied modulation signal at the EXT
MOD input in RAD/V.
The modulation deviation entered with ɸM Deviation"ɸM Deviation" is achieved with 1
Volt (=U
peak
) of the input signal.
Note: The input voltage must not exceed 1.1 V
p
otherwise modulation distortions
occur.
Remote command:
[:SOURce<hw>]:PM:SENSitivity? on page 784
Mod External Coupling
Selects the coupling mode ("AC" or "DC") for the external modulation signal.
Note: Coupling for external feed via input EXT MOD 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>]:PM:EXTernal:COUPling on page 782
Ext. Impedance
(Source "External" only)
Sets the impedance for the external modulation signal, applied at the EXT MOD con-
nector.
You can select 600 Ohm or high (>100 kOhm).
This setting affects all analog modulations which use the external modulation signal.
Remote command:
[:SOURce<hw>]:INPut:MODext:IMPedance on page 743
5.5.12.5 Pulse Modulation (PM)

lator and R&S SMBV-K23, Pulse Generator.
