LNR Up Converter Model UC14M-D5/D6 Manual

This manual contains operating and maintenance instructions for Up Converter Model UC14M-D5/D6 manufactured by LNR Communications Inc. The LNR model UC14M-D5/D6 is a RF frequency translation product, which provides uplink RF frequency translation functions in a single unit (1 3/4″) high. Its function is to up-convert an RF input frequency range of 70 MHz, or 140 MHz, to the standard C-Band Intelsat transmit (14.0-14.5 GHz) frequency spectrum.

The UC14M-D5/D6 will address any frequency within the stated transmit bandwidth in 125 KHz stepped increments, for D5 models, or 1 KHz stepped increments for D6 models. The IF bandwidth is intended for operation within a 54 MHz (40 MHz optional) bandwidth centered at 70 MHz (Fo +/- 27 MHz) or within a 72 MHz bandwidth centered at 140 MHz (Fo +/- 36 MHz). Due to its low phase noise and high frequency stability characteristics.

The model UC14M-D5/D6 may be used as a stand alone up converter, as a single thread transmit unit satisfying the frequency translation component requirements for an earth station, or in redundancy with either LNR 1:1 protection switch option or in one for one “switchless” redundancy configuration.

The UC14M-D5/D6 is completely self-contained, requiring only AC power to operate. The unit is housed in a standard size rack mountable chassis. All operational controls and indicators are located on the unit front panel. The on / off switch, line cord and all remote control and monitoring function accessibility are located on the rear panel. Local (front panel) controls are presented in an alpha-numeric menu driven format, via a “back lighted’ LCD display. Individual functions are accessed via front panel keypad switches.
