Analogue MOD/DEM (1U) TCU Series

The range of FM modulators and demodulators supplied by Elber to its proper clients have, since the beginning, maintained their efficacy, the robustness and performance which have no equals in the world market. Extremely flexible, it responds to all the client's requirements offering excellent performance, without giving up the simplicity in use.
Continuous research together with the great experience in the field of radio transmission techniques allows Elber to evolve these devices to a most high level of professionalism.
To stay updated with the latest innovations in the technological world market, Elber has finalized a complete highly engineered restyling of the analogical equipment.
A single board, based on innovative technologies with complete digital processing of the band base signal, is able to receive one analogue video input and four audio signals and provide directly in the output the IF modulated 70 MHz signal.
The default audio sub-carrier values are at 7.5MHz, 8.065MHz, 7.020MHz and 8.590MHz. However, on request, the sub-carriers can be re-located according to specific needs.
The demodulator board is designed in a particular way.
Besides the substantial space reductions (one single board can do the tasks previously done by four different ones), the advantages of this solutions are: Important reduction of the loss and the deterioration in time of which the "purely" analogical equipment usually suffers; Firm stability of the performance in time and in differences in temperature; Enabled/disable of the Pre-emphasis / De-emphasis networks from the front panel; Entire software programming of the Audio and Video signal levels; Direct monitoring through incorporated keypad and display of different values (Video signal level, Audio signal levels, FM deviation level, Level of the IF signal received from the demodulator); Accurate design modernized with positioning of the connectors on the rear panel.
The programming and the monitoring of the main parameters, apart from being done through the local interface (keypad and display on the front panel), can also be made remotely through an RS485 interface.
