The DAKS System is a low cost, portable, and easy-to-use dielectric assessment system kit that combines the DAK technology with the miniature portable R60 and R140 vector reflectometers from Copper Mountain Technologies. The direct and rigid connection of the probe to the reflectometer allows the probe to be moved to the media under test after calibration, greatly simplifying measurements in the lab. The reflectometer communicates directly with the DAKS software via a USB port. The system is highly accurate and is especially recommended for use in specific absorption rate (SAR) compliance laboratories for routine measurement of the dielectric properties of the tissue simulating liquids directly inside the phantom. The DAKS package includes a 3rd-party vector network analyzer (VNA), the Planar R140 or R60 from Copper Mountain Technologies. The DAKS probes, modified DAK-3.5 or DAK-12 probes, are equipped with N-type connectors. The DAKS is delivered with the probe mounted on the VNA and ready to use.
