the mgtr-ii is a small, lightweight, field portable, gps satellite receiver system specifically designed to perform end-to-end tests of line protection schemes, with megger smrt, mprt and pulsar relay test systems. the mgtr-ii provides a precise programmed output pulse (pop), with 100 nanoseconds of resolution. this output pulse provides a trigger synchronization of two or more smrt, mprt or pulsar test systems to less than ±1 µ sec of the universal time coordinated (utc).

the mgtr-ii consists of a twelve-channel gps timing receiver integrated with proprietary microprocessor-controlled timing and interface logic. the mgtr-ii simultaneously tracks all available gps satellites. the microprocessor-controlled timing and interface logic derives precise timing information. in addition, the mgtr-ii provides a standard 1 pulse per second (pps), and ascii serial time message, external event time-tag, an irig-b serial time code output signal and most importantly, a programmable output pulse for performing end-to-end tests.

the unit comes with a 50 foot (15.2 m) long cable and all-weather, high-performance, high noise immunity antenna with an integrated low-noise preamplifier. the antenna comes with a 4 inch tall antenna mount.

control of the mgtr-ii is through a standard rs-232 serial connection. software is provided to communicate to, and control the mgtr-ii unit.
