turnkey test systems for the management of SAR (Specific Absorption Rate) and human body phantoms for use in performance testing of wireless devices

IndexSAR have been active for a number of years in manufacturing compliant SAR testing systems using industrial-sized robots. The SARA-C is the first SAR test system not to require a large, complex industrial robot. By implementing novel techniques the system still uses the advantage of upright, full head, phantom geometry, successfully used in SARA2. By not implementing a robot, and using a limited amount of simulant liquid the cost of ownership is considerably reduced. The same configuration will allow the measurement of small base stations and pico-cells for localised SAR as required in EN50383.

The SARA-C robot is a 4-axis machine - X, Y and Z along with the ability to rotate a probe about its axis. The construction is largely non-metallic except for the stepper motors, which act remotely from the measurement area using non-metallic toothed belts. The SARA-C robot is mounted on a wooden stand bench. It uses low- dielectric fixtures to mount test devices and validation antennas as in the SARA2 test system. The robot is PC controlled via a USB link. Data are transferred from the probe via an optical cable. For reporting, test data can be exported directly as a Word document. The system is supplied with software and validation hardware to make compliant SAR measurements according to IEC 62209 part 2 and EN50383. Thanks to the speed of IndexSARs unique probe amplifier, Fully compliant head & body tests take less than 12 minutes making the system ideal for either development, or compliance testing.

The total system size is 500 x 720 x 1500mm. (Excluding PC and controller).
