Lnb Operation; Block Up Converter (Buc) Input; Monitor And Control (M&C) - Comtech EF Data LPOD PS 1.5 Installation And Operation Manual

LPOD C-, X-, or Ku-Band Outdoor Amplifier / Block Up Converter (BUC)
Introduction
• The +5.8V, -5.8V, +7.8V and +13.5V outputs are used to operate the M&C
board and other overhead functions.

1.4.5 LNB Operation

Either LPOD package style may be ordered with an optional internal 10MHz
reference and Low Noise Block (LNB) converter bias tee. With these options
installed, the user has control of the bias tee enable (LNB On/Off) as well as the
DC bias voltage (On/Off).

1.4.6 Block Up Converter (BUC) Input

The LPOD translates an L-Band input carrier to the desired output frequency (C-,
X-, or Ku-Band). LO frequencies are as follows:
Band
5850 to 6650 MHz
C-Band
5950 to 6700 MHz
Insat C-Band 6725 to 7025 MHz
X-Band 7900 to 8400 MHz
Ku-Band 14.00 to 14.50 GHz
Ku-Band-W 13.75 to 14.50 GHz
Unlike most BUCs, no DC bias voltage should be provided on the center
conductor of the L-Band coax. In addition, the LPOD is available with an internal
10 MHz reference. As, such, no 10 MHz reference is required on the center
conductor of the L-Band coax. If a reference is provided on the coax, the internal
reference will detect and lock to it.
1.4.7 Monitor and Control (M&C)
The LPOD includes a microprocessor-based system that provides monitoring and
control of the essential parameters of the unit. The user interfaces with the unit
through the M&C system via the remote control/discrete communications port.
