ANSI C63.19 HAC Workshop with
DASY5 Air at PCTEST Engineering Lab,
Columbia, MD, USA
At the ANSI C63.19 Workshop on Hearing Aid Compatibility Measurements, held on 10 October 2008, training and demonstration of HAC compliance testing was performed on a newly installed DASY5 AIR system at PCTEST Engineering Lab in Columbia, MD, USA.
One of the advantages of the new system is that the wireless device can be tested in the same configuration for RF E-field and RF H-field emissions as well as for T-Coil signals by simply changing the probes. Unlike other sensors, the SPEAG AM1D probe for the audio magnetic (T-Coil) fields incorporates a preamplifier and is fully immune to RF emissions from the wireless device. There is no need to replace the antenna with a coaxial cable, apply shielding or modify the wireless device for the T-Coil test. All orientations are measured with the same probe. The pre-installed signals allow fast scanning (only 1s per point with a voice signal and even faster rates with a sine signal). Also, user defined or standard signals such as the P.50 can be applied.
Some of our customers were not aware that SPEAG performs the filtering for the ABM1 and ABM2 in the time domain, and not the frequency domain, by convoluting the digital data stream with the filter parameters. Therefore, the data provided are fully compliant with the requirements of the standard. The visualization of the third-octave filtered values was conducted independently. To avoid future problems, the third-octave filtered values up to 10 kHz will be displayed in our next release.
The validation devices are now available with ISO 17025 traceable calibration for both the RF and T-Coil parts. New bands have also been added to our broadband RF dipoles for free space that have a high return loss over a wide band and do not require compensation of the reflected power. In addition, the SPEAG TMFS telephone magnetic field simulator with an extremely flat frequency response is available with numerical target values.

New Phantom - TwinSAM-Chin20
The growing number of mobile phones with antennas at the bottom of the device prompted the FCC to question the appropriateness of the current Twin SAM phantoms if peak absorption occurs in the upper part of the chin. In response, the latest draft of the IEEE1528 revision suggests alternative phantoms enabling accurate measurements for these exposure conditions, i.e., a probe angle of less than 20 degrees with respect to the normal surface.
Once more, SPEAG is the first company to offer a solution satisfying this new requirement.

New DASY4 and DASY5 Software Release
Based on our customers' valuable feedback, we are pleased to announce new releases of the DASY4 and DASY5 software, namely:
DASY4 V4.7 B71 and SEMCAD V1.8 B184
DASY5 V5.0 B119 and SEMCAD-X V13.2 B 87
The new DASY releases provide new features in the following areas:
Robot Movements (DASY5 only)
- The bug of the CS8 robot series leading to singularity problems in some rare instants could be eliminated by enhanced robot movement predictions in the DASY software. The speed settings for the single movement segments was further accelerated. Joint limits for the NEO systems have been relaxed providing more flexibility during measurements.
HAC RF & T-coil- updates to the latest standard versions ANSI C63.19-2006 and ANSI C63.19-2007
- visualization of the frequency response mask corrected to 300 - 3000 kHz
- program feedback for compliant distance setting
- increased measurement accuracy by compensating the effect of the dielectric material of the Test Arch on the electric field at close distances
- new HAC Arch phantom model for easier definition of measurement settings
- updated predefined files
SAR- updated predefined files and listing/setting for communication systems
Universal (Pseudo-Vector) Probes (DASY5 only)
- After successful completion of a research project, SPEAG is proud to announce a new probe type. Vector probes are the most accurate and the only truly universal probes, i.e., vector probes are the only probes that measure without additional isotropic errors in different media if sensitivity/ConvF, sensor angles and boundary compensation parameters are calibrated for the corresponding medium. Furthermore, vector probes provide much useful additional information: E- and H-field polarization of the near-field and far-field; information about amplitude and directions of RF currents inside devices; information about the cause of parasitic coupling, i.e., what couples from where to what.
In summary, vector probes are universal probes and a great analysis tool. They should be used wherever great precision is needed, field polarization must be validated or parasitic currents detected. The measurement time compared to isotropic probes is only increased by just more than a factor two (minimally three measurements at different angles need to be taken at each measurement point).

Spectral processing and evaluation is in accordance with the requirements of ANSI-PC63.19 for ABM1, ABM2, spectral response, signal level, etc.
SCS108: Extended Scope of Calibration
SPEAG is pleased to announce that the scope of the calibration services of our SCS108 accredited calibration laboratory has been extended to (valid as of
October 1, 2005):
- Calibration of dosimetric probes (EX3DVx type) in the frequency range
3 - 6 GHz - Calibration of system validation dipoles in the frequency range 3 - 6 GHz
- Calibration in air of HAC dipoles
As with the the previous scope, the frequency validity of a ConvF is extended to ± 100 MHz for DASY V4.4 and higher.
Call for Participation in Round-Robin Test
for DASY4 Customers
The general concept of the envisioned round-robin SAR testing is to use two mobile phones (DUT) having typical SAR distributions together with the SAM-Twin phantom filled with the head-tissue simulating liquid, whereby the two phones and the liquid would be supplied by SPEAG. Each laboratory would follow a measurement protocol defined and described in detail by SPEAG.
The number of different SAR assessments (e.g. frequencies and DUT positions) will be chosen such that the measurement time does not exceed 1 working day per laboratory. Participation fee and the duration of the round-robin exercise will strongly depend on the number of interested laboratories and will be announced later.
If you would be interested to participate, please send an e-mail to support@speag.com
