Tektronix 528A 波型監視器
The Tektronix 528A is a NTSC evision Waveform Monitor that is particularly well suited for monitoring signals from camera outputs, video system output lines, transmitter video input lines, closed-circuit TV systems & educational TV systems using a 30 frame （60 Hz field rate）, 525 line scan. Either of two video inputs may be selected from the front panel & displayed. FLAT, IRE, CHROMA & DIFF GAIN frequency response positions permit observation of various signal characteristics. A DC Restorer maintains the back porch at an essentially constant level despite changes in signal amplitude, Average Picture Level, & color burst.
