The LT51 Line Tester is a portable handheld battery powered instrument. It combines the features of several pieces of test equipment such as a Selective Level Meter / Spectrum Analyser, Distortion Analyser, Oscillator and Handheld DMM in the one small lightweight package. It is the ideal instrument for testing the analog interfaces of digital exchanges and PCM multiplexers. The LT51 is also very well suited to testing the carrier and information signals used in Power Line Communication (PLC) equipment..
