Sat Redundancy Switch (Vb272 And Vb273 Option Module For Vb220); Tuning Setup - BridgeTech VB20 User Manual

6.16 SAT Redundancy Switch (VB272 and VB273 Option
module for VB220)

6.16.1 Tuning setup

The redundancy switch requires two additional blades, a VB272 and a VB273 in the
same chassis. The Redundancy tab is located next to the corresponding SAT tabs.
Both of the RF outputs on the VB273 blade must be connected into the corresponding
inputs on the VB272 blade
The redundancy switch needs two identical signals delivered over two different
mediums, that will have to be connected into each IF input. Each IF input will have to
be tuned into the same transponder for the redundancy switch to work properly.
The 70 Mhz IF signals on input #1 and input #2 are up-converted to L-Band at the
fixed frequency 1094 Mhz. To tune to this frequency set the LNB local osc setting to
zero and set Transponder frequency to 1094 Mhz for both VB272 satelite inputs.
