Signal analyzers add narrow-band measurement support options

June 23, 2016 // By Graham Prophet
Anritsu has added signal analyzer options to its range, with differing frequency spans, to support narrowband measurement requirements for wireless devices. The updated MS2840A offers extended low phase noise options and support for millimeter-waveband transmitter and antenna measurements

The MS2840A signal analyzer product line gains frequency models at 3.6 GHz, 6 GHz, and 26.5 GHz, in addition to the existing 44.5-GHz model, offering narrowband measurement performance in a middle-range signal analyzer/spectrum analyzer platform. With a dedicated low phase noise option, the 3.6-GHz and 6-GHz models maximise close-in SSB phase noise performance that exceeds the performance of certain high-end models, as well as new option functions such as the built-in signal generator offered by the previous MS2830A series.


Many existing signal analyzers/spectrum analyzers on the market have the wideband performance required to support increasing common LTE and W-LAN measurements, but lack the narrowband measurement performance required for developing and manufacturing oscillators for various wireless applications. To meet the increasing demand for a low-cost platform with better performance than other high-end models, Anritsu has pushed development of new functions for its middle-range Signal Analyzer MS2840A, emphasizing narrowband measurement performance by targeting more frequency options, an order-of-magnitude better SSB phase noise performance, built-in signal generator, etc., supporting a versatile measurement platform.


This SSB phase noise performance upgrade has sufficient margin for evaluating spurious and phase noise of oscillators in wired and wireless equipment, which could only be evaluated previously using large and expensive dedicated phase noise measuring instruments and spectrum analyzers. Additionally, installing options such as the signal generator enables easy all-in-one MS2840A wireless TRx evaluations.
