Switching unit

GTS0220

This unit is used for the computer controlled switching of microwave signals in the frequency range DC … 18 GHz.

Design

The switching unit is housed in a 3 U 19“ subrack with very good RF shielding and consists of the following sub-assemblies:

-    relays SP12T, SP6T
-    control logic
-    power supply module
-    IEEE488 interface

All the necessary signal, power supply and earthing connections are provided at the rear.
The mains switch is located on the front panel.

Control

The unit is controlled via an IEEE488 interface.

Special features

The I/O boards are monitored in a processor routine.
A status string can also be requested at any time via the control interface.
The unit is constructed using a modular approach utilising 19” plug-in sub-assemblies which enable ease of installation and maintenance.
