and full remote monitor and control (M&C) capabilities (including Ethernet and
serial).
1.3.3
Built-in Redundancy Controller
The LPOD has the ability to function as a 1:1 (one backup for one primary)
redundant controller in a redundant mode without the use of an external device.
The optional redundancy configuration is implemented by attaching a ganged
waveguide/coax transfer switch(es) to the input and output connectors of the
amplifiers, using a combination coaxial cable and waveguide kit.
When the backup LPOD is commanded into redundant mode, it monitors the
online LPOD for faults and status, and automatically maintains a configuration
based on the online unit.
A faulted online unit may be disconnected and replaced without affecting the online
power amplifier.
1.3.4
“Smart BUC” Functionality
Comtech EF Data’s unique approach to L-Band/RF frequency conversions
eliminates DC and 10 MHz from the input coax. This simplifies redundant and
multi-carrier operation. Full 13.75 to 14.5 GHz Ku coverage and 5850 to 6725
MHz C band coverage is offered while supporting industry standard FSK
modem/BUC communications, as well as Comtech EF Data proprietary
commands.
Both LPOD models have a self-contained power supply, eliminating the
requirement for the modem to supply the BUC voltage on the center conductor
of the RF cable, simplifying multi-carrier operation and modem spares
maintenance.
1.3.5
Data Logging Capability
To greatly enhance system maintainability, the LPOD includes a built-in data
logging capability. By recording critical operational parameters (such as
temperature, output power, mute status, etc.) at time stamped intervals, the
