Anritsu has extended its Signal Analyzer MS2840A product line by adding three new frequency models - 3.6 GHz, 6 GHz, and 26.5 GHz to its current 44.5-GHz model supporting excellent 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 have excellent close-in SSB phase noise performance that exceeds the performance of other makers’ expensive high-end models, as well as new option functions like the built-in signal generator offered by the previous MS2830A series.
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.
Standard built-in signal analyzer functions support versatile measurements, including instantaneous spectrum observation, Frequency vs Time, Phase Variation vs Time, and Spectrogram displays. Both digital and analog wireless modulation signals can be evaluated by installing vector modulation signal analysis software, analog measurement software, as well as amplifier noise figure (NF) measurement functions into this analyzer family.
These three new models expand the Signal Analyzer MS2840A series to include options from 9 KHz to 3.6 GHz, 6 GHz, 26.5 GHz and 44.5 GHz. This platform has standard built-in functions for efficient measurement of Tx characteristics, including spurious, adjacent channel leakage power, spectrum mask, and frequency count. The versatile measurement platform of this signal analyzer makes it well suited for developing and manufacturing wireless equipment and devices.
Connecting the 26.5 GHz or 44.5 GHz model to a High Performance Waveguide Mixer, such as the MA2806A (50 GHz – 75 GHz) or the MA2808A (60 GHz – 90 GHz), or an external mixer ( ≤ 325 GHz) expands the measurement frequency range easily and leverages the inherent excellent sensitivity and dynamic range of this series. This configuration supports wide-dynamic-range measurements, as well as eliminates image-response effects when measuring wideband signals to implement efficient measurement for millimeter-wave wideband wireless equipment, such as wireless backhaul, automobile radar, and WiGig. It also allows for accurate evaluation of side-lobe characteristics of millimeter-wave radar antennas requiring high sensitivity.
