The Tektronix VM700 Video Measurement Test Set is a complete video monitoring and measuring instrument which can be used for automatic monitoring, as well as for manual measurements. The user can select a display of numeric values to confirm the quality of the signal path, or may select graphic displays for more detailed analysis. The Tektronix VM700 performs most standard televideo measurements automatically, including those specified in RS-250B/EIA-250C, NTC-7, and RS-170A. These measurements can be compared with user-defined limits and an alarm message generated when these limits are violated. New graphic displays are provided by the Tektronix VM700 for measurements such as signal-to-noise ratio and group delay, enabling the user to better understand (and improve) the transmission path.
