Anritsu Co. has enhanced its MS271xB family of economy microwave spectrum analyzers with specialized demodulation hardware and pre-written test routines for six popular wireless system configurationsfixed and mobile WiMAX, W-CDMA/HSDPA, cdmaOne, CDMA2000, EVDO and GSM/GPRS/Edge.

Covering 9kHz to 7.1GHz, 9kHz to 13GHz and 9kHz to 20GHz frequency ranges and delivering best-in-class dynamic range (100dB) and phase noise, the MS271xB family is said to quickly and precisely measure wireless components to increase production yields and lower the cost of test.

The three models in the MS271xB family support 13 new measurement options. The options cover RF measurement and demodulation, and are software test programs with pre-written test routines. Each test option features a long list of measurement functions with displays showing both measured data and computed parameters.

Ease of use has also been improved. A new Limit-Line creation capability has been added to the Anritsu Master Software Tools, which allows the user to create and modify display limit lines, make changes or compare them to actual signals. A Broadcast Spectrum limit version is available for transmitter testing to FCC standards.

The zero-span function now offers digital time markers, allowing RF power vs. time measurements to be made with improved accuracy. In addition, the marker function is now scrollable. Measurement speeds, remote I/O data transfer, and button response times are all faster, according to the company. For test automation creation, MS271xB programmable test functions are now available on LabVIEW, permitting easy test writing with high-level languages.

The MS271xB family measures 242mm x 372mm x 339mm and weighs 5.6kg. The analyzers provide 256Mbyte compact flash drive, 2Gbyte USB flash drive, Ethernet and USB2.0 connectivity to archive setups, update firmware and transfer results.

Pricing starts at $12,950 for the MS2717B (9kHz to 7.1GHz), $16,950 for the MS2718B (9kHz to 13GHz) and $19,950 for the MS2719B (9kHz to 20GHz). Delivery of the spectrum analyzers and new options is 6 weeks ARO.
