Not all conversations are meant to be heard - but they won't likely escape the IQC5000A Series. It continuously records 100% of both allied and unfriendly signals delivered by its signal analyzer RF front end down to the limit of the instrument's sensitivity. Dual-channel capability lets users record time-synchronous uplink and downlink transmissions or record the same channel in different physical locations to understand how signal characteristics change as the transmitter moves through the environment.
