Note(s):
*: According to SPEAG’s Technical Report, “MIF Verification”, Doc # TR-FB-12.09.04-1, issued date: 9/4/2012. E-field probes are
calibrated with specified uncertainty according to ISO 17025 as described in their calibration certificate. The MIF according to the
definition in ANSI C63.19 is specific for a modulation and can therefore be used as a constant value if the probe has been PMR
calibrated.

6. System Validation
The test setup was validated when first configured and verified periodically thereafter to ensure proper function.
The procedure provided in this section is a validation procedure using dipole antennas for which the field levels
were computed by numeric modeling.
Procedure
Place a dipole antenna meeting the requirements given in ANSI C63.19-2011 in the normally occupied by the WD.
The dipole antenna serves as a known source for an electrical and magnetic output. Position the E-field probe so
that the following occurs:

‧   The probes and their cables are parallel to the coaxial feed of the dipole antenna

‧   The probe cables and the coaxial feed of the dipole antenna approach the measurement area from opposite
    directions

‧   The center point of the probe element(s) is 15 mm from the closest surface of the dipole elements.
Scan the length of the dipole with the E-field probe and record the two maximum values found near the dipole ends.
Average the two readings and compare the reading to the expected value in the calibration certificate or the
expected value in this standard.

Notes:
1) Delta (Deviation) % = 100 * (Measured value minus Target value) divided by the Target value. Deltas within ±25% are
    acceptable, of which 12% is deviation and 13% is measurement uncertainty.
2) The maximum E-field or were evaluated and compared to the target values provided by SPEAG in the calibration certificate
    of specific dipoles.
3) Please refer to the appendix for detailed measurement data and plots.

7. Average Antenna Input Power & Evaluation for Low-power Exemption
An RF air interface technology of a device is exempt from testing when its average antenna input power
plus its MIF is ≤17 dBm for any of its operating modes. If a device supports multiple RF air interfaces,
each RF air interface shall be evaluated individually.

9. Modulation Interference Factor (MIF)
The HAC Standard ANSI C63.19-2011 defines a new scaling using the Modulation Interference Factor (MIF) which
replaces the need for the Articulation Weighting Factor (AWF) during the evaluation and is applicable to any
modulation scheme.
The Modulation Interference factor (MIF, in dB) is added to the measured average E-field (in dBV/m) and converts
it to the RF Audio Interference level (in dBV/m). This level considers the audible amplitude modulation components
in the RF E-field. CW fields without amplitude modulation are assumed to not interfere with the hearing aid
electronics. Modulations without time slots and low fluctuations at low frequencies have low MIF values, TDMA
modulations with narrow transmission and repetition rates of few 100 Hz have high MIF values and give similar
classifications as ANSI C63-2007.
Definitions
ER3D, E-field probes have a bandwidth <10 kHz and can therefore not evaluate the RF envelope in the full audio
band. DASY52 is therefore using the “indirect” measurement method according to ANSI C63.19-2011 which is the
primary method. These near field probes read the averaged E-field measurement. Especially for the new high
peak-to-average (PAR) signal types, the probes shall be linearized by probe modulation response (PMR)
calibration in order to not overestimate the field reading.
The evaluation method or the MIF is defined in ANSI C63.19-2011 section D.7. An RMS demodulated RF signal is
fed to a spectral filter (similar to an A weighting filter) and forwarded to a temporal filter acting as a quasi-peak
detector. The averaged output of these filtering is called to a 1 kHz 80% AM signal as reference. MIF measurement
requires additional instrumentation and is not well suited for evaluation by the end user with reasonable uncertainty
It may alternatively be determined through analysis and simulation, because it is constraint and characteristic for a
communication signal. DASY52 uses well defined signals for PMR calibration. The MIF of these signals has been
determined by simulation and is automatically applied.
MIF values were not tested by a probe or as specified in the standards but are based on analysis provided by
SPEAG for all the air interfaces (GSM, WCDMA, CDMA, LTE). The data included in this report are for the worst
case operating modes. The UIDs used are listed below:

A PMR calibrated probe is linearized for the selected waveform over the full dynamic range within the uncertainty
specified in its calibration certificate. ER3D, EF3D and EU2D E-field probes have a bandwidth <10 kHz and can
therefore not evaluate the RF envelope in the full audio band. DASY52 is therefore using the \indirect"
measurement method according to ANSI C63.19-2011 which is the primary method. These near field probes read
the averaged E-field measurement. Especially for the new high peak-to-average (PAR) signal types, the probes
shall be linearized by PMR calibration in order to not overestimate the field reading.
The MIF measurement uncertainty is estimated as follows, for modulation frequencies from slotted waveforms with
fundamental frequency and at least 2 harmonics within 10 kHz:
    •   0.2 dB for MIF -7 to +5 dB,
    •   0.5 dB for MIF -13 to +11 dB
    •   1 dB for MIF > -20 dB

10.      HAC RF Emissions Test Procedure
The following are step-by-step test procedures.
a) Confirm proper operation of the field probe, probe measurement system and other instrumentation and the
   positioning system.
b) Position the WD in its intended test position.
c) Set the WD to transmit a fixed and repeatable combination of signal power and modulation characteristic that is
   representative of the worst case (highest interference potential) encountered in normal use. Transiently
   occurring start-up, changeover, or termination conditions, or other operations likely to occur less than 1% of the
   time during normal operation, may be excluded from consideration.
d) The center sub-grid shall be centered on the T-Coil mode perpendicular measurement point or the acoustic
   output, as appropriate. Locate the field probe at the initial test position in the 50 mm by 50 mm grid, which is
   contained in the measurement plane, refer to illustrated in Figure 1. If the field alignment method is used, align
   the probe for maximum field reception.
e) Record the reading at the output of the measurement system
f)   Scan the entire 50 mm by 50 mm region in equally spaced increments and record the reading at each
     measurement point. The distance between measurement points shall be sufficient to assure the identification of
     the maximum reading.
g) Identify the five contiguous sub-grids around the center sub-grid whose maximum reading is the lowest of all
   available choices. This eliminates the three sub-grids with the maximum readings. Thus, the six areas to be
   used to determine the WD’s highest emissions are identified.
h) Identify the maximum reading within the non-excluded sub-grids identified in step g).
i)   Convert the highest field reading within identified in step h) to RF audio interference level, in V/m, by taking the
     square root of the reading and then dividing it by the measurement system transfer function, established in
     5.5.1.1 Convert this result to dB(V/m) by taking the base-10 logarithm and multiplying by 20.
     Indirect measurement method
     Replacing step i), the RF audio interference level in dB (V/m) is obtained by adding the MIF (in dB) to the
     maximum steady-state rms field-strength reading, in dB (V/m), from step h). Use this result to determine the
     category rating
j)   Compare this RF audio interference level with the categories in Clause 8 (ANSI C63.19-2011) and record the
     resulting WD category rating
k) For the T-Coil mode M-rating assessment, determine whether the chosen perpendicular measurement point is
   contained in an included sub-grid of the first scan. If so, then a second scan is not necessary. The first scan
   and resultant category rating may be used for the T-Coil mode M rating.
     Otherwise, repeat step a) through step i), with the grid shifted so that it is centered on the perpendicular
     measurement point. Record the WD category rating.
