PRODUCTSCAPABILITIES | 3 NON-DESTRUCTIVE ADEC SYSTEM detect counterfeit electronics within secondsThe Advanced Diagnostis of Electronic Components (ADEC) system provides a state-of-the-art counterfeit detection capability that performs rapid and reliable detection of counterfeits and other cyber-physical threats, such as maliciously altered parts. ADEC is a proven major breakthrough for counterfeit detection that has been developed by Nokomis to address the evolving threat that counterfeit and maliciously altered parts pose to modern technologies. ADEC assesses the internal circuitry of Integrated Circuits (ICs) through automated analysis of unintended radiated electromagnetic emissions that necessarily change due to part counterfeiting or malicious modifications. ADEC has been specifically engineered to enable 100% inventory testing to support large scale inventory testing, vendor pre-ship testing, and vendor qualifications. The rapid test speed supports thorough testing of critical components utilized in the defense, critical infrastructure, energy, and aerospace industries.The ADEC system is offered in two configurations, a four-channel and a two-channel system. The four-channel system offers state-of-the-art high speed processing and test throughput to support large scale inventory testing. The two-channel configurations are designed to handle low volume ADEC SYSTEM SPECIFICATIONSOperating Environment Desktop/BenchtopMajor System Components Signature Analyzer and IAEOperating System Microsoft Windows 10Signature Library Software UpdateablePower Requirements 110 VACComponent Scan Speed 3-5 SecondsFrequency Range 30 MHz through 1 GHzOperating Temperature Range -20ºC to 50ºCpart testing, such as at specialty maintenance depots and supporting testing laboratories.

PRODUCTSCAPABILITIES | 5 The ADEC Integrated Antenna Enclosure is a bench top test chamber specifically designed for collecting extremely low power Radio Frequency (RF) energy over a wide frequency range. The IAE provides electromagnetic shielding to isolate emissions from the part under test. The unique shape of the IAE allows for maximum reception of emitted RF energy from Integrated Circuits (ICs) and/or populated Printed Circuit Boards (PCBs). The antenna receiving this energy is integrated into the enclosure to ensure part registration consistency. The parts that are to be tested are inserted using a drawer at the base of the unit. Inputs to the part under test are provided through integrated bulkheads that have been engineered to ensure signal integrity for measurement repeatability. Emitted signals from the part under test are captured by the receive antenna and sent to the Signature Analyzer for acquisition and analysis.INTEGRATED ANTENNA ENCLOSURE (IAE) INTEGRATED ANTENNA ENCLOSURE SPECIFICATIONSEnclosure Size 13.5 in x 29.6 in x 16.24 inEnclosure Door Size 7 in (W) x 5 in (H)Door Operation Manual / Pneumatic operation optionalEnclosure Weight ~59 lbsFrequency Range 10 MHz through 6 GHzShielding Effectiveness > 80 dBCables and Connectors Provided for ADEC Signature Analyzer Connection with the Integrated Antenna Enclosure
