The MS27102A is a remote spectrum monitor designed to mitigate interference problems, and find and identify any illegal or unlicensed signal activity. The 20 MHz instantaneous FFT bandwidth on the MS27102A allows for wideband real-time captures of signal activity for subsequent post-processing. This monitor is designed for outdoor environments in applications such as jail/prison monitoring, facility security, RF lab testing, illegal transmitter detection, or Positive Train Control (PTC).
