nal levels in the 1 Vp-p range. Digital displays are more limited and can only display a couple of gray levels or a handful of pre-defined colors. These dis- plays normally accept TTL video signals in the 4 Vp-p range.

Analog Video and Sync Parameters

If you are entering a digital video format, skip this section of the manual and go on to the “Digital Video Parameters” section. If you are working with an analog video display, set DVST to zero. Enter the correct analog video signal type for the AVST com- mand. Both monochrome and color signal types are supported.

The following figure shows a typical video wave- form for either a monochrome or RGB color display:

Blanking

❖A few displays require an inverted waveform with negative-going peak video and positive going sync tips. The 801G* will not properly drive these types of displays.

The AVSS parameter sets the peak-to-peak swing of the video portion of the composite waveform. This swing includes any blanking pedestal that may be present and excludes any sync pulses that may be
