Remote command:
[:SOURce<hw>]:PULM:POLarity on page 984
Threshold USER4-6 Input/Threshold Pulse Input
Sets the high/low threshold in volts for the signal at the USER4-6 connectors.
The input signal is defined with the parameter Signal. The same threshold applies for
all 3 connectors and any input signal (e.g. external pulse modulation or trigger signal).
Remote command:
[:SOURce]:INPut:USER:PULM:LEVel on page 951
Impedance Pulse Input
Selects the input impedance for an external pulse modulation signal.
Remote command:
[:SOURce<hw>]:PULM:IMPedance on page 984
8.8.4.2 AM, FM and PhiM Modulation Settings
Access:
► Select "RF" > "Amplitude Modulation/Frequency Modualtion/Phase Modualtion".
The "FM", "Φ" and "AM" tabs contain the parameters per modulation type.
Since you need to determine an LF signal source for all modulations, "Source" and
"State" are described in general. These parameters apply to the modulation modes
AM, FM and ΦM. The following description explains the specific settings for the
appropriate modulation modes.
State
Option: R&S SMW-B9 - enabled in "System Config > Mode = Standard".
Option: R&S SMW-B10 - enabled in "System Config > Mode = Standard/Advanced".
