Delivering the highest levels of performance available in a handheld RF spectrum analyzer, the Field Master Pro MS2090A instrument gives field engineers and technicians unparalleled measurement accuracy previously reserved for only benchtop instruments.

  • Interference hunting and spectrum clearing – fast sweep speeds a low distortion front-end and the Real Time spectrum analyzer combine to quickly identify interfering signals. A special interference finder option adds AM/FM demodulation with audio output plus interfering source triangulation on a digital map to pinpoint and identify the location and source of interference.
  • Broadcast transmitter analysis – a comprehensive range of transmitter measurements – including: harmonic, spurious, occupied bandwidth, channel power, and adjacent channel power – ensures conformity to regulatory requirements
  • Microwave radio links – with a frequency option up to 54 GHz and exceptional sensitivity for dish alignment, power and modulation bandwidth can be verified during installation or maintenance testing with a waveguide horn antenna.
  • Satellite system monitoring – ideal for monitoring downlink signals to search for interference and noise
  • Pulse Radar Measurements – The wide bandwidth of the MS2090A enables detailed analysis of pulsed radar signals. In zero span, resolution bandwidth can be set as high as 40 MHz (option dependent), enabling a sweep time as low as 60 ns and amplitude measurements of pulses as narrow as 20 ns.
  • 5GNR base station measurement – validate the performance of the gNB base station with essential measurements that are in full compliance with 3GPP TS 38.104 V15, including:
    • frequency error
    • time offset
    • cell/sector ID
    • modulation quality
    • unwanted emissions
    • occupied bandwidth
    • adjacent channel leakage ratio
    • EIRP
    • transmitter harmonics and spurious
  • 5G coverage mapping – receive a clear representation of the signal strength of 5G transmitters over intended geographic area by continuously measuring RF data – including 5G channel power, EIRP, or RSRP – with results graphically displayed on a digital map or building floor plan.
  • Cable and Antenna measurements – Line sweep RF cables and antennas at base station locations with accessory S331P Site Master
