This E1 service tester is a multi-functional digital transmission system test device, designed for the installation test, engineering check and acceptance, daily maintenance of the E1 PCM line (G.703 2Mbit/s), mainly performing channel test, alarm analysis, fault finding and signaling analysis of the E1 (2Mb/s) line. This instrument mainly has following functions: · Support interface test of unbalanced 75Ω and balanced 120Ω. · Support HDB3 and AMI line coding. · Framed test under TX/RX mode (Out-of-service test). √ Framed/unframed end-to-end 2Mb/s BER testing. √ N×64Kb/s BER testing. √ Can monitor signal loss , AIS, frame loss, remote alarm, remote multiframe alarm, CRC multiframe loss, CAS multiframe loss, pattern loss alarm and bit, CODE, FAS, E-BIT error and so on. √ Clock slip measurement. · Online BER monitoring and timeslot analysis under RX HI-Z (high impedance) and through (bridge) mode. √ Performance test of bit error, coding error, FAS error, CRC4 error and E bit error. √ FAS and MFAS word analysis, timeslot busy or idle status display. √ Timeslot content monitoring, monitoring and display of 8-bit digital code word in any selected timeslot. √ Any 64kb/s tone channel monitoring. √ CAS (channel associated signaling) ABCD code monitoring and CCS (common channel signaling) TS16 timeslot monitoring. · Framed/unframed Round Trip Delay measurement. · 2M or 64kb/s signal of SDH transmission network automatic protection switching (APS) delay measurement. √ Simulate PCM terminal to perform various error insertion and alarm insertion. √ Transmit editable Si, Sa, A, FAS, CRC-4, MFAS, NMFAS and E- bit. √ Insert idle codes into one or more timeslots, and the idle code pattern is programmable. √ Insert single audio signals whose signal frequency and voltage are adjustable in one or more timeslots. √ Monitor any voice channel in the receiving terminal, single audio channel can measure signal voltage and frequency at the same time. √ CAS (channel associated signaling) ABCD code programming, CCS (common channel signaling) TS16 content programmable; · 2M signal level, frequency, offset measurement. · Transmission clock maximum deviation ±999ppm, effectively assess the clock restoration capability of the tested circuit. · Transmission clock: internal, interface, external 2M clock/signal (optional). · Test code type pattern: pseudorandom binary sequence (PRBS), fixed code and 16BIT user programmable code. · Bit, rate and other types of error insertion modes. · Real time display open circuit and short circuit status of the transmission circuit, effectively identify cable fault. · Has automatic test function at fixed time. · Perform the error analysis according to the G.821, G.826 and M.2100 standard of ITU-T. · Use the TestManager software for measurement result analysis, clean up, archiving and print output on PC via the serial port; · Handheld structure, durable design, suitable for carrying around and on-spot measurements. · High resolution backlight LCD, smart navigation mode operation displays in English. · Combine BERT, time-slot analysis, signalling testing, signal analysis, and other functions together. · Synchronization performance measurements give references to the more and more important system synchronization problem. · Up to 99 days continuance test performance. · Built-in NiMH rechargeable batteries and embedded with smart fast charger circuit. Can be charged with automobile cigarette lighter battery adapter. · Real-time clock and storages could be kept during a long time by power supply of the second spare battery without AC adapter and built-in NiMH battery module. · By using TestManager software, upgrading the embedded software of the instruments via the serial port to perfect the functionalities of the instrument and protect your investment.
