TEM Consulting

Hearing Aid Compatibility (HAC) has become an area of specialization. We offer testing to ANSI C63.19 and compliance design assistance. What to do your own testing? We offer near-field scanners for field maping as well as a combination T-Coil Magnetometer / Sound Level Meter.




Hearing Aid Compatibility Testing
	Full testing to ANSI C63.19-2001. Compliance evaluation to the 2003 FCC rules for mobile handset HAC. Testing includes: E-Field Emissions Scan H-Field Emissions Scan T-Coil Signal Amplitude T-Coil Frequency Response T-Coil Signal to Noise Sample Test Report .
E-Field	H-Field	T-Coil Signal Map

RF Near Field Scanning
		The TEM Consulting near field scanner is a high precisions positioner that supports the precise movement of field probes. Using our scanning positioner field maps of planes and volumes can be developed to assist engineers in antenna design, analyzing and solving EMC problems and mapping signal intensity.
