Switching unit

GTS0380

This unit is used for the computer controlled switching of RF 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 SP4T, SP10T
-    I/O boards
-    processor board
-    IEEE488 interface

All the necessary interface, power supply and earthing connections are provided at the rear.
The mains switch and the signal connection of the relay switches are located on the front panel.

Control

The unit is controlled via an IEEE488 interface.

Special features

T 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.
