Anritsu New Spectrum Analyzer with Enhanced Close-In Phase Noise Performance for R&D and Manufacturing of Narrowband Wireless Equipment and Device


Signal Analyzer MS2840A Sales Launch

Anritsu Corporation has announced the March 30 launch of its new Signal Analyzer MS2840A to expand the company’s line of signal and spectrum analyzers.

The released MS2840A has a frequency range from 9 kHz to 44.5 GHz and a built-in oscillator with greatly improved SSB phase noise performance. Additionally, it supports millimeter-wave band spectrum measurements using a High Performance Waveguide Mixer. The excellent close-in SSB phase noise performance enables a wide range of R&D and manufacturing applications, including microwave and millimeter-wave wireless equipment, 79 GHz band automobile radar, various oscillators, etc. Furthermore, the convenient built-in signal analyzer function supports analysis of instantaneous transmitter signals, while addition of various measurement software and options with noise figurer (NF) measurement functions supports detailed analysis and evaluation of transmitter modulation signals.

[Development Background]

Many recent spectrum analyzer models have wideband measurement functions supporting the increasing demand for LTE and Wireless LAN measurements. On the other hand, measurement of microwave wireless backhaul and VHF/UHF Private Mobile Radio (PMR) requires a spectrum analyzer emphasizing narrowband measurement performance, but most spectrum analyzers on the market supporting LTE do not match this requirement. Consequently, users requiring narrowband performance have either continued using older models dating from 10 to 20 years ago, or they have been forced to purchase very expensive high-end models. Makers researching and developing these wireless equipment and devices require a middle-range model emphasizing narrow bandwidth measurement performance.

[Product Details]

The Signal Analyzer MS2840A has been developed for R&D and manufacturing of wireless equipment and devices.

It has standard spectrum analyzer functions and covers a measurement frequency range from 9 kHz to 44.5 GHz. The close-in SSB phase noise performance is best-of-class for current middle range models* and the figures are equal to the highest-grade models (–123 dBc/Hz at 1 GHz measurement frequency and 10 kHz offset frequency). Additionally, the standard built-in signal analyzer function supports instantaneous monitoring of spectrums, as well as various measurements, including Frequency vs. Time, Phase vs. Time, spectrogram displays, etc. Adding vector modulation analysis software and analog measurement software options support evaluation of various digital and analog wireless modulation signals and also adds functions for measuring amplifier noise figure (NF) values.

Further, connecting the separately sold High Performance Waveguide Mixer enables spectrum measurements between 50 and 90 GHz for wideband wireless equipment, radar, etc.


  • SSB phase noise performance equal to high-end models
  • A wide frequency band is supported ranging from microwave wireless backhaul, requiring high phase-noise performance to measure close-in spurious of transmitter carrier, to VHF/UHF Private Mobile Radio (PMR).

  • Millimeter-wave band transmitter and antenna measurements
  • Connecting the High Performance Waveguide Mixer for millimeter-wave band measurements to the MS2840A not only supports high dynamic range measurements but also eliminates image-response effects at wideband signal measurement, making it ideal for measuring millimeter-wave wideband wireless equipment, such as wireless backhaul, automobile radar, WiGig, etc., as well as for evaluating millimeter-wave radar antenna sidelobe characteristics, which requires high sensitivity. Connecting the High Performance Waveguide Mixer (60 to 90 GHz) MA2808A to the MS2840A offers a SSB phase noise performance of –100 dBc/Hz at an offset frequency of 10 kHz in the 79 GHz band, and a high sensitivity of –150 dBm/Hz.

  • Multi-functions
  • Various convenient measurement functions for measuring Tx characteristics are built-in, including VHF/UHF-band wireless transmitter spurious, adjacent channel leakage power, spectrum mask, frequency count, etc. The built-in signal analyzer function supports Power vs. Time, Frequency vs. Time, Phase vs. Time, and spectrogram measurements. Further, the functions can be expanded by adding vector modulation analysis and analog measurement software options, as well as options supporting noise figure (NF) measurement.

The embedded OS is Microsoft Windows 7 (64-bit) running on a Core-i5* CPU with 8 GB of RAM and using SSD storage for optimum performance.
