Cable and Antenna Analyzer with Transmission Mode

The iVA-TMA is a software option that packages Transmission Mode measurement capability with the base iVA analyzer. Possessing additional testing sequences, the iVA – TMA includes Transmission Mode coupled with all existing features of the base iVA Cable and Antenna Analyzer.

Transmission mode enables two or more iVA’s to operate in a coordinated fashion to perform accurate swept insertion loss, antenna isolation and antenna radiation pattern measurements.

Sample Testing Scenario:

6 iVA’s with Transmission mode can be used to perform measurements on a multi-port antenna. This configuration covers all 36 transmission pathways (6x6), including return loss at each port (6 measurements) and the transmission loss between each possible pair of ports (30 measurements).

Transmission mode requires 2 or more iVA-TMA’s.


  • Directly measure insertion loss and isolation
  • Up to 7 units can be connected together via Bluetooth
  • Accurately measure transmission loss (Magnitude only)
  • 90dB dynamic range
  • Comes with all features of base iVA
