new photo r752 keyline 34p4 wide to trim 10p0 tall TSG131A multiformat signal generator. TSG131A multiformat signal generator low cost test signal generator tailored for service applications ebu n10 component levels supports betacam , mii , svhs, hi-8, gbr, and pal formats y, by, ry, gbr, or yc, pal and s connector outputs high accuracy test signal generation two channels of audio tone with channel one identification compact and lightweight tektronix is the worldwide leader supplying test equipment for the entire range of video and audio signal applications. our video and audio test portfolio consists of signal processing, generation, and measurement equipment for broadcast, cable, production, manufacturing, and transmission applications. the TSG131A is a low cost, multiformat test signal generator tailored for the testing and servicing of betacam , mii , gbr, svhs, hi-8, pal and monochrome 625/50 video equipment. the 10-bit digital signal generation and internal architecture allow generation of signals with the accuracy and stability until now available only in higher cost generators. with the TSG131A, you get all the signals you need to test video levels, linearity, frequency response, phase response, clamp performance, chrominance noise, picture monitor alignment, inter- channel timing, and more. for convenience in servicing svhs vcrs, the TSG131A pro- vides the pal and y/c outputs simultaneously, with the y/c outputs available both from bnc connectors and the standard 4-pin s-connector. two channels of 1 khz audio tone are provided on balanced xlr outputs. these phase locked tones are easily identified with the selectable id pulse in channel one. all this comes in a package size small enough not to clutter the service bench. and for field servicing, the TSG131A fits nicely in a briefcase with the rest of the necessary service tools. the TSG131A is part of a growing line of flexible, low cost service equipment from tektronix. for signal generation needs, consider the tsg111 for pal systems or the tsg121 yc/pal generator for systems operating with pal or y/c formats. composite signal monitoring requirements are handled by our 1711x and 1731 waveform monitors and 1721 vectorscope. the 1761 component/composite waveform/vector monitor fulfills the signal monitoring role for mixed component and composite facilities.
