The Audio Interference Analyzer (AIA) is a hardware interface to evaluate the Modulation Interference Factor (MIF) and Probe Modulation Factor (PMF) of RF signals in the frequency range 698 – 6000 MHz as per the HAC standard ANSI C63.19-2011. It is operated with DASY52.8.4 via a USB interface. Conducted signals can be measured with high precision and repeatability. Direct digital readings with 0.01 dB resolution allows comparison of different modulations not only with respect to the MIF, but also for the weighted power RFaudio interference potential (API), which is of interest for possible exemptions from RF scanning. Measurements can also be used to verify the presence of correct transmission modes.
In addition, the AIA can be used as an omni-directional ultra-wideband antenna when not connected via USB. We are pleased to announce the release of the optimized high frequency dielectric probe DAK-1.2 and an important software upgrade.
