TX120A - Multi-Function Test Instrument

The TX120A is a low cost, multi-function test instrument, primarily for determining the suitability of twisted copper pairs for use by Pair Gain Systems, ISDN and HDSL but with application in the testing of such pairs for normal telephone services. In many cases, the TX120A eliminates the need for expensive instruments such as Pulse Echo Testers (PETs) and Transmission Testers.
