Option 010: Vector Network Analyzer Time Domain

  • visualize error-corrected time domain reflection or transmission responses
  • remove unwanted responses with gating
  • view time and frequency domain data simultaneously
  • transform the frequency domain to the time domain or vice versa

Option 378: Over-the-Air (OTA) 5G NR

  • capture over-the-air 5G NR FR1 and FR2 signals
  • demodulate downlink primary and secondary synchronization signals
  • scan results of key performance indicators
  • optimize Inter-RAT handovers for overlapping 5G and LTE networks

Option 233: Spectrum Analyzer

  • analyze the spectrum with four traces and different detector types
  • select radio standards and set limit lines
  • perform channel power and field strength measurements including antenna factors
  • record data and play it back later

Option 350: Real-Time Spectrum Analyzer (RTSA)

  • capture signals with 100 MHz of real-time bandwidth
  • detect masked small and intermittent signals
  • view the density spectrum, spectrogram, or real-time spectrum
  • capture signals as short as 5.52 µs with 100% probability of intercept (POI)

Option 215: TDR Cable Measurements

  • identify the location of faults along cable lines with time-domain reflectometry (TDR)
  • characterize the nature of faults by analyzing changes in impedance
  • measure distance-to-fault and TDR in one line sweep
  • expose mismatch issues and poor connections
