Operating Manual 1407.6062.32 ─ 08
"Negative"
The pulse generator is triggered on the negative slope of the external
trigger signal.
SCPI command:
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.
SCPI command:
Pulse External Input Impedance
Selects the input impedance (10
kOhm or 50
Ohm) for the external trigger and gate signal
input (PULSE EXT).
SCPI command:
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.
SCPI command:
5.4.14 Sweep Mode
5.4.14.1
Overview
The R&S Signal Generator 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 trig-
gering mode (automatic, internal and external).
Sweeps and List mode can not be activated simultaneously, they deactivate each other.
