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 801
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 802
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.
Remote command:
[:SOURce<hw>]:PULM:OUTPut:SYNC[:STATe] on page 799
5.5.14 RF Sweep and List Mode
5.5.14.1 Overview
The R&S SMBV offers three different sweep types (frequency sweep, level sweep and
LF sweep) to be activated alternatively. Each type has 6 modes which differ with
respect to the sweep cycle mode (continuous, individual and step-by-step) and trigger-
ing mode (automatic, internal and external).
●
Sweeps and list mode can not be activated simultaneously, they deactivate each
other.
●
Activating a sweep mode immediately disables NRP-Z Level Control.
Vice versa, a running sweep mode blocks "NRP-Z Level Control". It can not be
activated.
●
If you want to remain at a specific frequency or level value during a sweep, enter
the value directly in the status bar. The sweep stops immediately.
