1. Digital video channel outputs — Female DB25 connectors that provide
parallel digital output of the three video channels. The output is balanced
ECL with 10 data pair and one clock pair per channel.
2. Trigger output — A 75
Ω
BNC connector that provides a frame-rate TTL
pulse that can trigger an oscilloscope or other equipment.
3. Analog video channel outputs — 75
Ω
BNCs, two for each component video
channel. When the TSG 1001 is generating NTSC composite video, the
composite signal will be available on one, two, or all three of the channels,
depending on the source program; see the SDP1000 manual for more
information.
4. Sync outputs — 75
Ω
BNCs that provide only the bi-level or tri-level sync
pulses of the active video format.
5. Power switch — Push-push on/off.
6. Fuse — Medium blow: 2A for 230V operation, 4A for 115V operation.
7. Power cord receptacle.
8. Clock input — A 78
Ω
“BNO” connector for input of an external balanced
ECL clock signal. The clock signal may be encoded with a frame-reset pulse.
Permits the use of an external oscillator, typically in a Tektronix SPG 1000
HDTV Sync Generator.
