Channel Power mode

Cable and Antenna Analyzer with Channel Power Analysis Mode

The iVA-CPA is a new solution that adds Channel Power measurement capability to the existing base iVA analyzer. The iVA-CPA comes with all the features of the base iVA analyzer and includes Channel Power mode for additional functionality.

Channel Power mode enables the user to determine the total RF power between any two frequencies in a spectrum monitor trace. Measurement modes include CW signal and modulated signal.


  • Measurement bandwidths of up to 75 MHz allowed
  • Levels ranging from -100 to +15 dBm
  • Both modulated and continuous wave signals supported
  • Comes with all features of base iVA Cable and Antenna Analyzer

1 Occupied bandwidth and Adjacent Channel Power Ratio features to be included in future release of application software.
2 B is the occupied bandwidth of the measured signal in MHz.
3 Accuracy specification assumes that the measured signal is the only signal present during a measurement. The iVA's accuracy may be degraded if other signals are present during a Channel Power measurement, especially if the aggregate RF power at the test port exceeds the iVA's compression point.
4 Future releases of Unify will allow the user to define up to 10 simultaneous measurement channels across the frequency range of interest.
