A number of other options are also available with the Cell Master MT8212B.
An interference analyser measures interfering signals and displays their standard type and bandwidth so that field technicians can quickly identify interfering signals to reduce dropped calls and coverage problems.
The Cell Master 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 GSM, AMPS, iDEN, and TDMA network applications, the Cell Master MT8212B can be equipped with a channel scanner to display currently available channel power.
The analyser can be used as a wireline physical layer analyser as well.
T1 and E1 interface tests include 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.
All these enhancements expand the testing capabilities of the Cell Master family.
The MT8212B can perform all the measurements of the traditional Cell Master analyser.
Incorporating the same cable and antenna analyser found in the industry-leading Site Master family, the MT8212B quickly locates small, hard-to-identify faults before major failures occur.
A built-in power meter performs highly accurate power measurements to reduce signal holes and interference.
Cell Master MT8212B's spectrum analysis capability allows users to locate, identify, record, and solve communication systems problems from 100kHz to 3GHz.
The MT8212B maintains the accuracy and simplicity found throughout the Cell Master family.
It 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 these measurements can be made on signals as low as -135dBm.
By utilising the field-proven Site Master design, the MT8212B can withstand the day-to-day punishment associated with field use.
The MT8212B also has a standard transflective colour display that makes viewing easy - even in direct sunlight and at wide viewing angles.
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.
The integration of the CDMA transmitter analyser option into the MT8212B also 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 the parameters can be displayed in graphical format or text only.
The Cell Master MT8212B also provides users with flexibility when demodulating cdmaOne and cdma2000 1xRTT signals.
In addition to making measurements in the traditional manner by connecting Cell Master MT8212B to the base station, an over the air (OTA) measurement option allows field technicians to demodulate the cdmaOne and cdma2000 1xRTT signals while on the road.
