Applications

• Component Analog Video Equipment Maintenance

The TSG131A is a low cost, multiformat test signal generator tailored for testing and servicing of Betacam, GBR, S-VHS, 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 S-VHS VCRs, the TSG131A provides 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.
