2 Preparing the Extension Unit for Use
This chapter gives an overview of the front panel controls and connectors of the
R&S
ZVAX24 extension unit and gives all information that is necessary to put the unit
into operation and connect it to the network analyzer.
Chapter
outlines a typical application example for the
extension unit (pulse profile measurement). Chapter
describes the available options and their use. For further information including
remote control reference refer to the online help system of your network analyzer or its
printed/printable version delivered on CD-ROM.
2.1 Front Panel Tour
The front panel of the extension unit provides the standby key, two type A USB connec-
tors, and RF connectors for ports 1, 2, and 3.
2.1.1 Standby Key
The standby key connects/disconnects all internal modules of the extension unit to/from
the DC supply voltages generated by its internal power supply.
The two LEDs indicate whether the extension unit is ready to operate (green LED on) or
in standby state (yellow LED on).
It is recommendable to switch the extension unit to standby state or switch it off by the
rear panel AC power switch if it is not used for some time.
2.1.2 USB Connectors
The USB connectors of type A (master USB) may be used to connect e.g. a calibration
unit, a keyboard, mouse or other pointing devices, a printer or an external storage device
(USB stick, CD-ROM drive etc.). A second pair of equivalent USB connectors is located
on the rear panel of the extension unit.
