The Trigg/Gate In can be used for external triggering or for an input pulse that needs reshaping. The Sync Out is a square wave +1.5Vp into a 50Ω load. The Aux Out is a fixed pulse +2.5Vp into 50Ω load. The Pulse Out is the main fully controlled output with amplitudes of 0.5Vp, 1.5Vp & 5Vp into a 50Ω load, plus a 10Vp unterminated output.

Note: Significant cosmetic imperfections, missing bezel however functions as intended.
