詳細(xì)資料：

The Tektronix 1720 Series Vectorscopes provide comprehensive television signal monitoring for NTSC applications. These versatile instruments are light weight, half-rack width and have bright CRTs for video signal monitoring. The instruments exceed normal monitoring capabilities, and their unique features make them even more powerful when operated in tandem with other Tektronix test equipment. Each monitor has its own advanced feature set and the proven 1700 Series family performance to provide more monitor for the money. These monitors do the job faster, better and easier at an economical price.
