Switching unit

GTS0660

The switching unit is used for the processor controlled switching of RF signals in the frequency range DC … 500 MHz.

Design

The switching unit is housed in a 3 U 9.5“ subrack with very good RF shielding and consists of the following sub-assemblies:

-    transfer relays
-    I/O boards
-    processor board
-    IEEE488 interface
-    manual control modul

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 a IEEE488 interface and via a manual control module with a LC display and pushbutton which is integrated on the front panel.

Special features

The I/O boards are monitored in a processor routine.
The selected crosspoints as well as the I/O fault messages are displayed on the manual control module.
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.
