The Spectrum Analyzer/Signal Analyzer MS2840A has an upper measurement frequency limit of 44.5 GHz and its carrier close-in SSB phase noise performance is overwhelmingly best-of-class for middle range models. The MS2840A supports measurements across a wide frequency band ranging from applications such as microwave wireless backhaul, requiring high phase-noise performance to measure transmitter carrier close-in spurious, to VHF/UHF private mobile radio (PMR). Connecting the High Performance Waveguide Mixer MA2806A/MA2808A to the MS2840A not only supports wide dynamic range measurements from 50 to 90 GHz but also eliminates image-response effects at wideband signal measurements, supporting millimeter-wave wideband wireless applications, such as wireless backhaul, automobile radar, WiGig, etc., as well as evaluation of millimeter-wave radar antenna sidelobe characteristics, which requires high sensitivity. Additionally, spectrum measurements up to 325 GHz are supported by connecting the External Mixer (Harmonic Mixer) MA27xxC series.

  • High close-in phase noise performance:
    • –123 dBc/Hz (at 1 GHz center frequency, 10 kHz offset frequency with all frequency models)
    • –138 dBc/Hz (at 1 GHz center frequency, 10 kHz offset frequency with 3.6 GHz and 6 GHz models, meas.)
    • –140 dBc/Hz (at 150 MHz center frequency, 10 kHz offset frequency with 3.6 GHz and 6 GHz models, meas.)
  • Full range of built-in versatile and convenient functions for evaluating wireless Tx characteristics, such as Channel Power, Occupied Bandwidth, Adjacent Channel Leakage Power, Spectrum Mask, Frequency Counter, etc.
  • Frequency vs. Time, Power vs. Time, Phase vs. Time, Spectrogram, CCDF, etc., measurements up to 44.5 GHz using Signal Analyzer function (Resolution Bandwidth: 125 MHz max.)
  • Vector modulation analysis and analog measurements (FM/ΦM/AM)
  • Built-in signal generator option supports all-in-one wireless TRx and BER measurements
  • Measurement of phase noise characteristics of wireless equipment and local signal sources with built-in wireless using Phase Noise Measurement Function (option) making use of MS2840A excellent phase noise performance
  • Accurate noise figure (NF) measurements up to 44.5 GHz using Noise Figure Measurement Function (Option)
