MS2840, suitable for manufacturing and R&D of narrowband wireless equipment and devices

Anritsu Corporation announced the launch of the new signal analyzer MS2840A on March 30 to expand its signal and spectrum analyzer lineup.

The newly released MS2840A has a frequency range of 9 kHz to 44.5 GHz and features a built-in oscillator with significantly improved SSB phase noise performance. In addition, it supports millimeter-wave band spectrum measurements using a high-performance waveguide mixer.

The excellent near-SSB phase noise performance enables applications in a wide range of R&D and manufacturing fields, including microwave and millimeter-wave radio equipment, 79 GHz band automotive radar, and various oscillators. Furthermore, the convenient built-in signal analyzer function supports instantaneous transmission signal analysis, and options for noise figure (NF) measurement and various measurement software are added to support detailed analysis and evaluation of transmitted modulated signals.



Recently, many spectrum analyzers have broadband measurement capabilities such as LTE and wireless LNAs, which are constantly increasing. On the other hand, while microwave radio backhaul and VHF/UHF private mobile radio (PMR) measurements require spectrum analyzers focused on narrowband measurement performance, most LTE-supported spectrum analyzers on the market do not meet these requirements.

Therefore, users who require narrowband performance had to continue using old models from 10 to 20 years ago or purchase very expensive high-end models. Manufacturers researching and developing such wireless equipment and devices need a medium-performance model focused on narrow bandwidth measurement performance.

The MS2840A signal analyzer was developed for the manufacturing and R&D of wireless equipment and devices.

It features standard spectrum analyzer functions with a measurement frequency range of 9 kHz to 44.5 GHz. Its near-SSB phase noise performance is currently the best in its class among mid-range* models, with figures equivalent to top-of-the-line models (1 GHz measurement frequency and 10 kHz offset frequency -123 dBc/Hz).

In addition, the built-in signal analyzer supports instantaneous spectrum monitoring as well as various measurements, including frequency versus time, phase versus time, and spectrogram displays. With the addition of vector modulation analysis and analog measurement software options, it supports the evaluation of various digital and analog radio modulated signals and includes a feature to measure amplifier noise figure (NF) values.

In addition, by connecting a separately sold high-performance waveguide mixer, it is possible to measure the spectrum in the 50 to 90 GHz range for broadband wireless equipment, radar, etc.
