2.2.7 EXT PULSE GENERATOR IN / OUT
Input connector for pulse generator signals from external pulse generators. The two pulse
generator signals labeled 1 and 2 can be set to control the pulse modulators in the exten-
sion unit (options R&S ZVAX-B271, R&S ZVAX-B272, R&S ZVAX-B273).
The pulse generator signals from the CASCADE IN or the EXT PULSE GENERATOR
IN inputs can be fed to the PULSE GENERATOR OUT connectors; see
figure 3-3 on
page 24 .
The pulse modulators are controlled either via the EXT PULSE GENERATOR IN or via
the CASCADE IN connector. See
chapter 2.2.6, "CASCADE IN" , on page 14.
The pulse PULSE GENERATOR OUT signals are also compatible with external pulse
generators with a 50
Ω
load impedance.
2.3 Putting the Extension Unit into Operation
This section describes the basic steps to be taken when setting up the extension unit for
the first time.
Risk of instrument damage
Before switching on the instrument, make sure that the following conditions are met:
●
Instrument casing is in place and all fasteners are tightened.
●
All fan openings are unobstructed and the airflow perforations are unimpeded. The
minimum distance from the wall is 10 cm.
●
The instrument is dry and shows no sign of condensation.
●
The instrument is operated in the horizontal position on an even surface.
●
The ambient temperature does not exceed the range specified in the data sheet.
●
Signal levels at the input connectors are all within the specified ranges.
Failure to meet these conditions may cause damage to the instrument or other devices
in the test setup.
