Анализатор качества электроэнергии

Power Quality Analyzer ADS-1DF Datacom Tester is applicable to the project construction, project checking & accepting and daily maintenance & testing in the data transmission system. The performance of this tester is reliable & stable, and its function is completed and its volume is small. And it is also with large screen, English menu and easy operation. ADS-1DF Datacom Tester conduct testing for the following: 2Mbit/s interface data channel, V.24,V.35,V.36,X.21,RS-449,RS-485,EIA-530,EIA-530A, the same direction 64kbit/s interface digital channel, and four-wire romote FSK stimulated channel. It has been widely used in the access network, transmission network, numeric data network and etc. Major FeaturesLCD large-screen display, 320*240 lattice, backlight, LED indicatorHand held, auto configurationMulti-task operation at one timeStore 20 test results and 9 test configurations, with power-off memoriesPC operation, store, analysis, printProgrammable timerAlarm and histogram analysisSoftware updatingMajor FunctionsFor 2Mbit/s: Service-interrupted error testing Online error testing Framed and unframed signals generation and reception 2Mbit/s unframed error performance testing 2Mbit/s framed N×64kbit/s channel error testing Bit error, coding error, frame error, CRC error and E bit error testing Signal loss alarm, AIS alarm, framed remote alarm, multi-framed remote alarm, out-of-frame, and pattern loss alarm Frequency offset testing Line signal level and frequency testing Voice channel signal level and frequency testing Pattern slip testing Straightforward signaling Audio frequency testing Loop circuit delay testing Automatic protection switching time testing (APS) Sound monitoring Signal state display.
