7.2. USE OF THE 2032 VIDEO OUTPUT
108
The VIDEO OUTPUT of the
.
2032 is intended primarily for use with video plotters, to
obtain a hard copy of the 2032 Display. The screen image is output via the VIDEO
OUTPUT socket on the rear panel of the 2032, and follows the European CCIR Stan-
dard for 625 lines interlaced video, (that is as PAL, but in black and white). It consists
of 312 lines non-interlaced, 50 fields per second, 1 V peak to peak, into 75
n.
Should a video monitor be connected to the 2032 VIDEO OUTPUT, the monitor must be
able to accept a video signal of 25 pictures/second, 625 lines (CCIR or PAL system),
and it must be underscanned such that the whole picture from the 2032 can be dis-
played.
