安立 Anritsu MT8815A 無(wú)線通訊測(cè)試儀

The MT8815A is the fastest and most accurate  phone tester for repair applications, and the only tester that supports all popular 2G, 2.5G, and 3G technologies in one unit, including a scalable platform providing investment protection by allowing installation of new wireless formats.

The MT8815A hardware platform covers a frequency range of 30 MHz to 2.7 GHz. When dedicated measurement software and hardware (options) are installed, this single platform supports evaluation of all the main transmission/reception test items for W-CDMA, GSM/GPRS/EGPRS, cdma2000 1xRTT (IS-2000), cdma2000 1xEV-DO, AMPS, and PHS terminals.

Advanced DSP (Digital Signal Processing) and parallel-measurement technology greatly reduce the time required for the production and testing of  terminals. Combinations of parameters for batch measurements are freely selectable, and the number of repeat measurements for each measurement can be set independently. The selected items for measurement can be batch-processed through one-touch operation, enabling easy, high-speed Pass/Fail evaluation on major test items including transmission frequency, modulation accuracy, transmission power, adjacent channel power, occupied bandwidth and BER. The standard GPIB and RS232-C interfaces enable the MT8815A to be used in existing automated production lines or to be configured by automatic test systems in maintenance sites.

T8820A覆蓋30MHz到2.7GHz的頻率范圍，遵照3GPPTS34.121的研究和發(fā)展及制造應(yīng)用，用于3GW-CDMAUE終端機(jī)作傳送和接收測(cè)試。它亦支持3GPP呼叫過(guò)程，允許在呼叫過(guò)程中功能測(cè)試及收發(fā)器測(cè)量。在對(duì)話時(shí)從終端機(jī)發(fā)出的聲音信號(hào)可以回波送返，從而作一簡(jiǎn)單聲音測(cè)試。功能30MHz到2.7GHz的頻率范圍高DSP和平行測(cè)量科技使測(cè)試更快捷3GPP呼叫過(guò)程；注冊(cè)；發(fā)源,終止等12個(gè)收發(fā)器測(cè)量項(xiàng)目包括模組分析；鄰近通道功率比和遵照3GPPTS34.121的峰值編碼域
