The Camera Master is a digital, hand-held, battery operated meter that measures five different characteristics of the video signal from a CCTV camera or other video source, namely:
SYNC (40 IRE Units) Enables the camera to be set to the correct video
output level.
WHITE (100 IRE Units) Enables the camera Iris to be accurately adjusted
to the correct brightness setting.
COMPOSITE (140 IRE Units) Measures overall level of the video signal.
140 IRE Units = One Volt Peak to Peak.
COLOR BURST (40 IRE Units) Measures color burst amplitude on the Back
Porch of video. Used to adjust cable equalizers to offset cable slope
loss.
FOCUS Used to adjust camera for best focus on scene. Maximum meter reading
occurs at sharpest focus. No need for a TV monitor at the camera location.
The Sync, White, and Composite amplitude measures the sync- to-white
ratio and the overall video waveform amplitude on any part of an NTSC
or PAL video system, including camera origination, video levels in Distribution
Amplifiers, TV Switchers, Studios, Microwave and Satellite transmission
systems.
The small size of the Camera Master enables it to be taken directly
to the camera location, thus saving time and in many cases, reducing test
and installation manpower.
