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

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
