The MT 186(e)/ MT 188(e) are intended for evaluation, installation or troubleshooting 2/4 wire leased lines and 2 wire dial-up circuits. They are designed to measure analog impairment parameters over telecommunication circuits in conformance to ITU-T O standards.

• 20 Hz to 50 KHz Synthesized Sine Wave Generators.
• Ideal for the testing operation of telephone lines and leased/dial-up data circuits.
• Performs basic transmission line measurements (TIMS) and electrical parameter tests.
• Signal to Noise Measurement.
• Crosstalk, Power Influence, Return Loss Measurement.
• DTMF/MF/PULSE dial, loop hold capability, speaker and microphone.
