iVA Series

Cable and Antenna Analyzer

The iVA series Cable & Antenna Analyzer is an exciting new product from Kaelus that enables users to accurately measure and locate VSWR/return loss faults in their RF infrastructure. The wireless connectivity allows unprecedented measurement flexibility and opens up new & important possibilities in sweep testing and multi-port testing.The iVA is a rugged battery operated module that can be remotely controlled with any Bluetooth-enabled tablet, smart phone, laptop computer or any of our iPA series Portable Passive Intermodulation analyzers.


  • Reinventing site certification sweep testing, dramatically reducing test time on site
  • Directly measure insertion loss and isolation when using multiple iVAs. Measure calculated insertion loss with a single iVA and an RF short
  • Accurately measure swept VSWR/return loss and Distance-to- Fault in RF path
  • Simple and robust Bluetooth connection to a tablet PC or connect with USB or Bluetooth to a laptop computer
  • Connect directly to the device under test; eliminates the need for a phase stable cable in most cases
  • Uses the Kaelus customer-proven iPA reporting workflow & tagging features to facilitate a faster, simpler and more efficient workflow
  • With the Kaelus iPA controlling the iVA, your RL data can be combined with your PIM data into a single report. Reports are combined and completed on-site with no post-processing required
  • Simple to operate, highly intuitive software user interface with the unique ability to generate and complete the test report onsite
  • Geotag each test point, insert a Google Maps® snapshot directly into the report
  • Handy Spectrum Monitor mode for interference checking
  • Stimulus mode allows iVA to be used as a signal generator. Can be configured to cycle through a number of frequencies, with a user-defined dwell time at each frequency.
