IF Matrix MAS2050 from Novotronik
This matrix distributes 64 IF signals to 64 receivers in the frequency range 20 … 200 MHz without any blocking.

Design

The matrix is housed in a 12 RU 19“ subrack which provides excellent RF shielding and consists of the following sub-assemblies:

–    low noise amplifiers with high dynamic range
–    power dividers 32-way
–    solid-state switch boards 32×4
–    processor boards
–    LAN interface
–    manual control module (optional)
–    redundant power supply (optional)

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 matrix is normally controlled via a LAN interface.
Other control interfaces like RS-232, RS-422, RS-485 and IEEE488 are possible.

Special features

The power supply voltages and the I/O boards are monitored in a processor routine.
The selected crosspoints as well as the voltage and 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.
