GPR3000
unit
The
GPR3000 unit is designed for use with block
upconverter modules operating in the C,
Ku or DBS satellite frequency bands.
The
Unit contains single or separate dual circuitry,
each providing an L band route for the transmit
data signals, 10MHZ signals from a high
stability oven controlled crystal oscillator
used to lock the block up converter (BUC)
to, and a +24V DC supply to power the BUC.
All of these signals are inserted onto the
'composite' output for connection to the
cross-site cables. |
