Anritsu Co. introduces new options for its MS271xB series that take advantage of the economy microwave spectrum analyzers’ best-in-class phase noise of -110 dBc/Hz at 10 kHz offset (typical, 800 MHz) 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 analyzers via 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 colors. 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 troubleshooters to predict system EVM and BER.

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

Anritsu has also developed options for the MS271xB series to create a cost-efficient method to quickly and precisely measure the performance of TD-SCDMA components. One option includes a suite of measurements to quickly and accurately measure the RF of TD-SCDMA signals. Modulation quality of TD-SCDMA transmitters can now also be evaluated with the MS271xB series.

Covering the 9 kHz to 7.1, 13 and 20 GHz ranges, the MS271xB family meets most RF and microwave spectrum analyzer requirements. The excellent phase noise performance allows the instruments to measure most wireless local oscillators and synthesizers, while their superior dynamic range of 100 dB results in fast and precise testing of wireless components that require exceptional linearity. Designed with a 10 MHz demodulation bandwidth, the MS271xB family supports GSM, CDMA, W-CDMA, W-CDMA/HSDPA, EVDO and WiMAX measurements, in addition to TD-SCDMA. Starting US prices are $13,450 for the 9 kHz to 7.1 GHz MS2717B, $17,450 for the 9 kHz to 13 GHz MS2718B and $20,450 for the 9 kHz to 20 GHz MS2719B. Delivery of the spectrum analyzers and the new options is eight weeks ARO.
