Anritsu has introduced an on-screen coverage mapping option for its E series Spectrum Master, Site Master, and Cell Master handheld wireless analyzers. The option is designed to help wireless service providers, public safety users, land mobile radio operators, and government officials verify system coverage and perform spectrum clearing before installing new radio services. The add-on works with Anritsu’s SE332/SE362, MS2712E/MS2713E, and MT8212E/MT8213E analyzers.

With the option installed on one of these analyzers, users can map received signal strength indicator (RSSI) and adjacent channel power ratio (ACPR) levels. Intuitive color coding simplifies the interpretation. The update rate can be set in seconds or in distance, depending on user preference. The option supports both indoor and outdoor mapping. For indoor mapping, the option uses a start-walk-stop approach to ensure accuracy when GPS is not valid.

To support the option, Anritsu’s MapMaster free Windows map conversion program can convert the files from many map sources to special image files that contain GPS data. The map can then be uploaded to the analyzer via easy to follow menus. The overall amplitude accuracy, coupled with the GPS update rate, ensures accurate and reliable mapping results.

The Site Master SE332 and SE362 instruments are full-featured handheld analyzers for installing, provisioning, maintaining, and troubleshooting wireless basestation cable and antenna systems. With frequency coverage from 100 kHz to 6 GHz, the analyzers offer a typical sweep speed of 1 ms/data point, four hours of battery life, dual display capabilities, USB for data transfer, and touchscreen keyboards.

The MS2712E and MS2713E handheld spectrum analyzers cover the 100-kHz to 6-GHz frequency range as well. They also provide interference analysis capabilities and the ability to assess signal quality across a broad range of increasingly complex RF signals. They have a dynamic range of >95 dB in 10-Hz resolution bandwidth (RBW), a displayed average noise level (DANL) of –152 dBm in 10-Hz RBW, and phase noise of –100 dBc/Hz maximum at 10-kHz offset at 1 GHz.

The Anritsu MT8212E handheld basestation tester lets users perform most of the usual tests necessary to deploying, maintaining, and troubleshooting antennas, cables, transmitters, and other related equipment. The new mapping software option extends its usefulness by enabling the capture of RSSI and ACPR data for coverage analysis.

The Cell Master MT8212E and MT8213E handheld multi-function basestation analyzers combine all the tools required to deploy, maintain, and troubleshoot wireless basestations in a lightweight, battery-operated package (see the figure). They are economical solutions for 2G/3G/4G, WiMAX and ISDB-T basestation transmitter testing. Each instrument sweeps cables, makes power measurements, finds interference, troubleshoots signal quality, and verifies backhaul performance.
