Anritsu Corp. has unveiled what claims to be the first Mobile WiMAX handheld test solution designed for deploying, installing, and maintaining Mobile WiMAX networks.

Incorporated into Anritsu's BTS Master and Spectrum Master platforms, the Mobile WiMAX test capability provides field engineers, technicians and contractors with an easy and highly accurate method for conducting RF, demodulation, and Over-The-Air (OTA) measurements on WiMAX signals.

The Mobile WiMAX measurement capability has been designed into three options to provide users with flexibility when configuring their instrument. The Mobile WiMAX RF measurements option can be used to measure the transmitted signal strength and signal shape of a transmitter. When configured with the RF measurement option, the handheld analyzers can conduct channel spectrum, power versus yime (with 5ms and 10ms frame lengths), and ACPR measurements. RF summary screens can also be displayed with the option.

Engineers and technicians can use the Mobile WiMAX demodulator to analyze OFDMA signals and display detailed measurements for evaluating transmitter modulation performance. The measurement screens that can be displayed are constellation (QPSK, 16 QAM, 64 QAM), spectral flatness, EVM versus subcarrier, EVM versus symbol, DL MAP with automatic decoding, and modulation summary.

In addition, a channel power monitor measurement is part of the Mobile WiMAX OTA option and allows a specific channel's power over time and specified interval to be analyzed. This feature can be combined with a GPS feature so that measurement data can include GPS location and time data for plotting on a map. Anritsu's Master Software Tools enables easy integration into MapInfo Professional and Microsoft MapPoint maps.

All the options can be used with the MT8222A BTS Master, and the Spectrum Master MS2721B, MS2723B, and MS2724B analyzers. Weighing less than nine pounds, the MT8222A is small, light and economical handheld solution for complete 2G/3G/4G base station testing. The MS2721B, MS2723B, and MS2724B are advanced ultra-portable 7.1-, 13, and 20GHz spectrum analyzers. Their broad frequency coverage and sensitivity, coupled with a wide selection of resolution bandwidths, make the MS272xB series suited for the most challenging field environments.
