Anritsu  has introduced new options for its MS271xB series that take advantage of the economy microwave spectrum analysers’ phase noise of -110dBc/Hz at 10kHz offset (typical, 800MHz) and make it easier to integrate the instruments into legacy manufacturing environments.

The MS271xB series has been designed to accurately measure the performance of wireless broadband components and devices, increase production yields, and lower the cost of production test.

Running on an external PC, the software controls any of the economy microwave spectrum analysers through an Ethernet or GPIB interface and combines multiple swept measurements into summary displays of phase noise performance. It provides multiple phase noise trace plots on the same scale, in different colours.

Phase noise plots can be smoothed and compared with user-created limit lines. The software also allows source jitter measurements to be displayed in seconds, degrees, or Hz. The method in which the data is collected and displayed by the software makes it easier for wireless broadband designers and trouble-shooters to predict system EVM and BER.

Anritsu has also enhanced the MS271xB series with a GPIB interface, which allows the economy microwave spectrum analysers to be easily integrated into legacy manufacturing test systems. A new front panel USB connector facilitates connection of flash drives.

Covering the 9kHz to 7.1, 13 and 20GHz ranges, the MS271xB family meets most RF and microwave spectrum analyser requirements. The good phase noise performance allows the instruments to measure most wireless local oscillators and synthesisers, while their dynamic range of 100dB results in fast and precise testing of wireless components that require high linearity.

Designed with a 10MHz demodulation bandwidth, the MS271xB family supports GSM, CDMA, W-CDMA, W-CDMA/HSDPA, EVDO and WiMAX measurements, in addition to TD-SCDMA.
