HAC T-Coil Extension for DASY5 AIR, PRO and NEO

Hearing Aid Compatibility (HAC) T-Coil Extension: Audio Band Magnetic Test of Wireless Devices according to ANSI-C63.19 Available for DASY5 AIR, PRO, NEO and DASY4

Contents Extends DASY5 with HAC RF extension for testing Audio Band Magnetic (ABM) signals. Combination covers all measurements required for emissions from wireless devices. Categorization of the wireless device with combined evaluation of RF and ABM measurements
Audio Magnetic Field Probe (AM1DVx) Active single sensor probe for both axial and radial measurement scans. Fully RF shielded, compatible with DAE, with adapted probe cup. ISO/IEC 17025 calibration service available.
Helmholtz Calibration Coil (AMCC) Allows calibration of the complete measurement setup
Audio Magnetic Measurement Instrument (AMMI) USB interface to PC
Probe signal digitization and power supply
Test signal generation for wireless device (via base station simulator)
Auto-calibration and interfaces to AMCC for complete setup-calibration

Software

DASY4/DASY5 integrated ABM field scan, processing, visualization & reporting:
Flexible new scan job with test signal selection
Predefined or user selectable test signals (e.g. artificial voice)
Spectral processing, filtering, weighting and evaluation according to
ANSI-PC63.19 (ABM1, ABM2, spectral response, signal level, etc.)

Predefined procedures for:
Calibration and Verification of setup
Scanning and interpolation to find optimum axial and radial positions
Evaluation of performance at determined or predefined positions

Postprocessing for interactive combined evaluation:
ABM (S/N), signal level, frequency response with interpolation
Combination with RF E-field and H-field scan results
Determination of  the optimum positions coordinates (axial and radial)
Documentation ready for inclusion into compliance report
Graphical User Interface allows inspection of scanned signal (incl. spectrum)
Accessories Telephone Magnetic Field Simulator (TMFS)
Remarks Base station simulator with audio input required (not included)
Test Arch phantom and phone holder available from HAC RF Extension
