Mountain Engineering and Technology ME-1002 Overview
The ME-1002 simulates three types of transmission line commonly used in short distance, interoffice digital telephone systems: 100W and 120W twisted-pair and 75W coaxial cable. It simulates the frequency dependent attenuation characteristics of these lines at the lengths recommended for output pulse mask testing by both US and European standards committees. Receiver input sensitivity can also be tested through the RJ-48 connector with simulated line loss ranging from 0dB to 18dB. The ME-1002 also simulates 0m to over 1200m of 75W coaxial cable. All line length settings are addressable in units of Feet, Meters, and dB of Attenuation at both 1.544Mb/s and 2.048Mb/s data rates.
In addition to simulating transmission lines, the ME-1002 provides a dedicated 50W signal output and a corresponding Smart TriggerTM output for easy and accurate oscilloscope viewing and mask verification of individual data pulses. To facilitate use in automated test environments, all ME-1002 functions can be operated either by front panel controls or through computer control via a standard RS-232 serial port. Options include a rack-mount chassis, battery back-up and an internal noise mixer.
