WiMAX options for Anritsu LMR Master

WiMAX is expected to be used as a backhaul technology for distributed land mobile radio networks.

The WiMAX test capability provides engineers, technicians and contractors responsible for public safety networks with an accurate method for conducting RF, demodulation, and over-the-air (OTA) measurements on WiMAX signals.

The 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, Anritsu's LMR Master S412E can conduct channel spectrum, power versus time (with 5ms and 10ms frame lengths), and ACPR measurements.

RF summary screens can also be displayed with this option.

Engineers, technicians and contractors can use the WiMAX Demodulation option to analyse 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.

For both Fixed and Mobile WiMAX signals, Anritsu offers the OTA measurement option.

With these options installed in the LMR Master S412E, users can make OTA measurements to spot check a transmitter's coverage and signal quality without taking the site offline.
