Kramer 810 Composite Video & s-Video Color Bar/Audio Tone Generator

The Kramer 810 is a bench and rack test source that puts a 75% color bar and a 1kHz tone onto a system so you can prove a signal path end to end. It feeds two composite outputs on BNC plus one s-Video output on a 4-pin connector, and a front switch flips the whole generator between PAL and NTSC.

Audio comes out as unbalanced stereo on a detachable 3-pin terminal block, with a trimmer for setting level against whatever the downstream gear expects. It runs on a 12V DC supply drawing 230mA, and ships with the supply and a mounting bracket so it can live permanently in a rack bay or under a desk in a machine room.
