Measurement chart showing a power vs. frequency chart with a linked waterfall chart. The x-axis shows the level in dBm the y-axis the frequency. In the waterfall chart the x-axis shows the time and the levels are color coded from blue (low level) till red (high level). The charts show 2 curves the green one is the current level and the red one is the maximum hold.

Measurements & Analysis

Mask overlay on the power vs frequency chart with 10 channels. Each channel has an expected level which is indicated as a straight line as well as an upper tolerance which is indicated as a dotted line. The 3rd and 5th channel are marked as red (alarm) as the signal in it exceeds the threshold. The signal in the 6th channel is at the expected level but does not exceed the upper tolerance so there is no alarm.

Alarming & Automation

  • Automatic Violation Detection (AVD)
    • Automatic detection of anomalies like interference or illegal spectrum usage
    • Based on:
      • AI compares trained reference situation with new data
      • Manual definition of upper and or lower thresholds
      • Reference level from wave-prop calculation (Input Tx database)
      • Auto calculation of thresholds from reference recording
    • Alarm triggering via email
    • Alarm history in alarm logs and alarm reports
  • AVD triggered actions NEW
    • AVD alarm automatically triggers measurement features on secondary receiver and unit(s)
    • Recording of IQ or Raw for and around the violated band/channel
    • Direction-finding from multiple locations to geolocate the source of the alarm
  • Automated measurement jobs
    • Pre-definition of measurement parameters, analysis features, time and area
    • Multi-band jobs: Individual parameters and measurement features per defined band
    • Automatic execution of job
    • Option for recurring jobs (minutely, hourly, daily, monthly)
    • On-demand jobs that can be initiated with a single click from the cockpit NEW
