ANRITSU has introduced the latest version of the Cell Master base station analyser, model MT8212B.

This version adds new capabilities such as a CDMA/GSM transmitter analyser, interference analyser, built-in source, channel scanner, and DS0/VF channel access, to the Cell Master design.

The integration of these additional test capabilities provides users with a single handheld instrument for the deployment, installation and maintenance of GSM and CDMA networks, weighing less than 2.3kgs.

The MT8212B can conduct all major RF measurements, such as channel power, frequency error, occupied bandwidth, and noise floor, on CDMA signals.

The integration of the CDMA transmitter analyser option into the unit allows it to demodulate cdmaOne and cdma2000 1xRTT signals.

Code domain power, pilot power, channel power, frequency error, waveform quality, pilot time tolerance, pilot Ec/Io and carrier feed through can be displayed with this option. All parameters can be displayed in graphical format or text only.

An Over The Air (OTA) measurement option allows field technicians to demodulate the cdmaOne and cdma2000 1xRTT signal, and for GSM applications the MT8212B has an option that allows the analyser to conduct traditional RF measurements for power and frequency error. The unit can also display time slot information on GSM signals.

A number of other options are also available. An interference analyser measures interfering signals and displays their standard and bandwidth so that field technicians can quickly identify interfering signals to reduce dropped calls and coverage problems.

The MT8212B can also be ordered with a built-in signal source for measuring the gain/loss of two-port devices, as well as be used for antenna isolation measurements and repeater tests.

For AMPS, iDEN, TDMA, and GSM network applications, the MT8212B can be equipped with a channel scanner to display currently available channel power.

The analyser can be used as a physical layer BER analyser, with E1 and T1 tests including DS0/VF channel access monitoring. A user manually selects each one of the voice channels (DS0/VF access) and monitors with the built-in speaker.

Cell Master's spectrum analysis capability allows users to locate, identify, record, and solve communication systems problems from 100kHz to 3GHz.

The unit has dedicated routines for smart measurements of field strength, channel power, occupied bandwidth, Adjacent Channel Power Ratio (ACPR), Carrier-to-Interference (C/I), and interference analysis. All of these measurements can be made on signals as low as -135dBm.

The MT8212B comes with a bright, daylight viewable wide angle transflective colour display, making viewing easy in any environment.

A built-in GPS receiver provides location (latitude, longitude and altitude) and UTC time information so that each trace can be stamped with location information.
