J103 — Accessory Connector
The accessory connector, J103, is a 9-pin D connector, (not RS-232
compatible). The connector provides an interface for video |/O and the
2714's sweep gate and sweep ramp signals. Terminations are shown
in Figure 8-1, and a discussion of each signal follows.
Within the signal discussions are bulleted instructions were prepared
to guide you through applications using the Accessory Connector
signals. The instructions were designed to be used consecutively, as

Pin 1 — External Video Input
Pin 1 enables you to introduce an external video signal to the 2714, in
effect giving it limited oscilloscope capabilities. It is also used to
introduce the frequency markers from the 1405 TV Sideband Analyzer
(see the previous discussion of J101).
