MRS-100 Tragbare Relay Station

The Mobile Relay Station MRS-100 is easy to use and has been designed for mobile applications. The small and very robust aluminium suit-case makes transportation of the MRS-100 very comfortable while perfectly protecting the equipment against harsh environments.

The MRS-100 can be equipped with different transmitters, receivers and data acquisition / processing modules to best meet the required application specific demands. Standard off-the-shelf configuration would include L- / S-Band receiver with switch-able demodulator-bandwidth, an all-IRIG bit-synchronizer / code converter, eight switch-able pre-modulation filters and an L- / S-Band transmitter, together with the appropriate antennas.

Transmitter / Receiver carrier frequency, demodulator bandwidths and pre-modulation filters can directly be programmed via front-panel controls. The bit-synchronizer is remote-programmable via RS-232 with up to eight different formats to be stored within the internal non-volatile Flash memory. Format can then be selected via front-panel thumbwheel switch. An integrated RSSI-Meter helps to easily qualify the received signal and to optimise antenna locations.

Strong emphasis has been put into the demand to give the user the provisions to use all integrated modules together as a complete Mobile Relay Station with Signal recovery as well as to allow the user the separate use of all modules, i.e. just the bit-synchronizer or to feed the internal transmitter with an “external” signal.

NOTE: There are several options available to meet application specific requirements. Please do not hesitate to send us your inquiry for your specific needs.
