The IDA-3106 Interference and Direction Analyzer is a compact, portable system designed for measuring and evaluating electromagnetic fields. It operates in the frequency range of 9 kHz to 6 GHz.
Function Description:
The IDA-3106 offers a variety of operating modes for sophisticated signal analysis. Its primary function is interference and direction analysis, enabling the identification and localization of signal sources. This is achieved through manual bearing determination or automatic horizontal scans, with bearings directly superimposed on an electronic map in Direction Finding mode for triangulation. Beyond direction finding, the device supports Spectrum Analysis, Level Meter, Time Domain (Scope), and I/Q Analyzer modes.
