Option SD/HD Setup 2 - Three-Wire Analog Video with Composite Sync
Use this setup for testing 3-wire component analog video signals (Y/G, Pb/B, Pr/R) with the composite sync signal on Y/G.
Set the triggering on the instrument to CH1 (the default trigger setting is CH4). This setup is simpler than the others
mentioned in this section, but limits noise measurement on Y/G to -65 dB (30 MHz noise bandwidth).
