3.5 Sync Signal Selection

The sync signals output on connectors JP12 through JP15 are individually programmable as composite sync (CS)
composite blanking (CB), vertical drive (VD), or horizontal drive (HD). Additionally, burst flag (BF) can be output on
JP12. These signals are identified next to sync select connectors JP8 thru JP11. Note that JP12 is the only connector that
has burst flag (BF) available for selection. JP8 selects sync signals for JP12, JP9 for signals on JP13 , etc.
Signal selection is accomplished by moving the jumpers on JP8 thru JP11 to select the desired output for JP12 through
JP15. For example, to output composite blanking on JP13, remove the jumper from CS2 of JP9 and place it on CB2 of JP9.
The BNC connector that is connected to JP13 now outputs composite blanking instead of composite sync.

3.6 Subcarrier Output Selection

To select subcarrier for output, connect one of the BNC connectors to JP5 or JP6 via its 2-pin connector (as previously
described for sync signal selection).
On JP2, move the jumper over to connect pins 1 and 2. Connect pins 2 and 3 on JP2 when subcarrier is not selected, to
keep subcarrier leakage at a minimum. It may be necessary to slightly readjust burst amplitude and SCH when sucarrier is
selected.

3.7 Operating the BSG-50

To operate the BSG-50 simply connect the desired output signals and power it up. A red LED above the power switch
comes on when the BSG-50 is powered up.
