Tektronix TSG130A Overview

Features & Benefits Low Cost Test Signal Generator Tailored to Service Applications Supports Betacam, MII, S-VHS, Hi-8, GBR, and Composite Formats BNC and S-connector Outputs High Accuracy Test Signal Generation Two Channels of Audio Tone With Channel One Identification Compact and Lightweight Black Burst Output (Option) NTSC Test Signal Outputs Applications Component Analog Video Equipment Maintenance The TSG130A is a low cost, multiformat test signal generator tailored for the testing and servicing of Betacam, MII, S-VHS, Hi-8, NTSC and 525/60 GBR 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 TSG130A, 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 and Hi-8 VCRs, the TSG130A provides the NTSC 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.

A dedicated black burst output is available as an option. This output is recommended for the service bench where an external reference signal is required for equipment fault diagnosis and adjustment.

All this comes in a package size small enough not to clutter the service bench. And for field servicing, the TSG130A fits nicely in a briefcase with the rest of the necessary service tools.
