Anritsu Company introduces three CDMA2000 1xEV-DO options for its Cell Master™ MT8212B handheld analyzer. Expanding the analysis capability to include on CDMA2000 1xEV-DO signals, the options allow the MT8212B to be used by RF engineers, maintenance personnel, and cell site technicians responsible for the deployment, maintenance, troubleshooting and optimization of CDMA2000 1xEV-DO basestations and networks.

In addition to the CDMA2000 1xEV-DO options, Anritsu also announces power monitor and bias tee options for the Cell Master MT8212B. The power monitor gives the Cell Master the ability to measure the power of wireless back-haul networks up to 50 GHz. Designed directly into the Cell Master, the bias tee is for applications in which both DC and RF signals must be applied to a device under test, such as a tower mounted amplifier (TMA).

The EVDO RF measurement option expands the Cell Master MT8212B’s measurement capability to include Pilot/Mac power, Pilot power, frequency error, measured bandwidth, idle/active activity, and idle/active data on CDMA2000 1xEV-DO signals. With the EVDO demodulator option, the Cell Master demodulates CDMA2000 1xEV-DO signals and displays code domain power as Mac code power or data power.

Among the advantages wireless professionals can realize with the Cell Master MT8212B in 1xEV-DO environments include:

• High-speed in PN (Pseudo Random Number) acquisition. Cell Master takes less than eight seconds for PN acquisition plus a full set of measurement. This is an advantage in noisy OTA situations when the test equipment can lose PN Sync easily.

• MAC CDP (Code Domain Power) Noise Threshold Line is shown graphically. This lets the user know at one glance how far the current noise threshold differs from the EvDO standard of -31.5 dB.

• Cell Master shows a Data CDP diagram, instead of just maximum/minimum data code powers. The diagram pinpoints exactly which sub-channel in the data channel has unusual power levels, and helps users determine if it is a hardware or software issue in the system.

• Cell Master does Rho Overall 2, which is a standard measurement parameter in the EvDO specification, as well as Overall EVM (Error Vector Magnitude), which is a combination of Rho Overall 1 and Rho Overall 2.

• Cell Master also measures RMS channel power. This power measurement incorporates idle/active percentage as well as the active/idle slot powers so users can see the average load on a transmitter.

The Cell Master’s vector corrected > 42 dB directivity after calibration results in the industry’s best measurement accuracy when conducting cable and antenna return loss measurements. Users can select between 130, 259 or 517 data points to assure optimal resolution and fault locations. Other specifications include < 500 ms sweeps for easier identification of intermittent, real-time problems, as well as ± 0.5 dB (typical) amplitude accuracy for high accuracy in channel power and adjacent channel power measurements. Cell Master MT8212B also achieves 𤹟 dBm typical DANL for low-level interference and reverse link signal analysis.

New options for the Cell Master MT8212B allow the analyzer to perform RF, demodulation and over-the-air (OTA) measurements.
