Genlock Function
This test verifies that the genlock function is operating correctly. The following
equipment is required for the test:
TV signal generator (TG700 mainframe with AGL7 module)
Waveform vector monitor
Three 75 Ω BNC cables
Two 75 Ω coaxial terminators
Perform the following procedure to verify that the genlock function is functioning
correctly.
1. Use a 75
Ω BNC cable to connect the REF connector on the sync pulse
generator to the BLACK 1 connector on the TV signal Generator (AGL7
module). See Figure 4-2.
2. Use a 75
Ω BNC cable to connect the other REF connector on the sync pulse
generator to the A connector on the waveform vector monitor. See Figure 4-2.
3. Use a 75
Ω BNC cable to connect the CH 1 connector on the sync pulse
generator to the B connector on the waveform vector monitor. See Figure 4-2.
4. Use the 75
Ω coaxial terminators to terminate the A and B loop through
connectors on the waveform vector monitor rear panel. See Figure 4-2.
