"Extern Gated"
The pulse generator signal is gated by an external gate signal.
Remote command:
[:SOURce<hw>]:PULM:TRIGger:MODE
on page 399
Execute Single Trigger
Initiates a single pulse sequence manually.
This function is enabled in "Single Trigger ", see Trigger Mode - Pulse Generator
Remote command:
[:SOURce]:PULM[:INTernal][:TRAin]:TRIGger:IMMediate

External Trigger Input Slope - Pulse Generator
(External Trigger only)
Sets the polarity of the active slope of an applied trigger signal.
"Positive" The pulse generator is triggered on the positive slope of the external
trigger signal.
"Negative" The pulse generator is triggered on the negative slope of the external
trigger signal.
Remote command:
[:SOURce<hw>]:PULM:TRIGger:EXTernal:SLOPe
on page 399
Gate Input Polarity - Pulse Generator
(Trigger Mode External Gated only)
Selects the polarity of the Gate signal.
The signal is supplied via the PULSE EXT connector.
"Normal" The pulse signal is generated while the gate signal is high.
"Inverse" The pulse signal is generated while the gate signal is low.
Remote command:
[:SOURce<hw>]:PULM:TRIGger:EXTernal:GATE:POLarity
on page 398
External Impedance
Selects the input impedance (10 kOhm or 50 Ohm) for the external trigger and gate
signal input (PULSE EXT).
Remote command:
[:SOURce<hw>]:PULM:TRIGger:EXTernal:IMPedance
on page 399
Use SIGNAL VALID as Pulse Sync
Configures the signal at the SIGNAL VALID connector (rear panel):
"selected" Indicates the validity of the RF signal at the output:
●
high: while the signal settles.
●
low: when it is stable (valid).
"cleared" Generates a single pulse at the beginning of a pulse sequence, e.g.
to synchronize pulse modulation.
