description of the pulse generator in the help system of your network analyzer.
See the following section for additional information.
3.3.5 EXT PULSE GENERATOR IN / OUT
IN/OUT connectors for external pulse generators.
The pulse modulators of the extension unit can be controlled either by the connected
R&S
ZVA/ZVT (via CASCADE IN ) or by an external pulse generator (via EXT PULSE
GENERATOR IN 1, 2).
The analyzer firmware allows to define
●
which generator signals shall be used by modulator 1, 2 and 3
●
which generator signals shall be fed to EXT PULSE GENERATOR OUT 1 and 2
The pulse PULSE GENERATOR OUT signals are compatible with external pulse gen-
erators with a 50
Ω
load impedance.
