- Page 3 DESCRIPTION: The CM-1S is an adaptor that is used with the CM-1 CAMERA MASTER meter to measure video levels on S video installations. The adaptor conveniently mounts on the two BNC connectors on the top of the CM-1 CAMERA MASTER and is self terminating for both channels of video information.
- Page 4 Position the CM-1 facing toward you with its BNC (female) connectors facing upward. Place the CM-1S adaptor above the connectors with the BNC (male) connectors facing down. Line up the BNC connectors to mate. Rotate the BNC (male) connectors so that the notches align with the BNC (female) connectors.
- Page 5 CABLE LOSS COMPENSATION: When cable loss or Color-Burst loss is excessive, consider utilizing an amplifier with appropriate cable equalization. With S video equalizers it is possible to completely compensate video cables of 1000’ or longer. THE KEY TO MEASURING SYSTEM PERFORMANCE: Two measurements (Sync Pulse and Color Burst amplitude), provide an exact and specific measure of the ability of any cable to transmit a quality picture.
- Page 6 Table 2 shows that there is a very serious loss of high frequency response as the S video cable extends beyond a hundred feet or so. Obviously, something must be done to be able to obtain high definition pictures at more than a few hundred feet. THE ANSWER TO S VIDEO LOSS! The answer to S video loss is to offset this loss by amplification and equalization to exactly replace the energy lost at each frequency.
