Report No.: 15I20402-S2D Issue Date: 5/4/2015 6. Test Procedures for all Technologies ANSI C63.19-2011, Section 7 This document describes the procedures used to measure the ABM (T-Coil) performance of the WD. In addition to measuring the absolute signal levels, the A-weighted magnitude of the unintended signal shall also be determined. In order to assure that the required signal quality is measured, the measurement of the intended signal and the measurement of the unintended signal must be made at the same location for all measurement positions. In addition, the RF field strength at each measurement location must be at or below that required for the assigned category. Measurements shall not include undesired properties from the WD’s RF field; therefore, use of a coaxial connection to a base station simulator or non-radiating load may be necessary. However, even then with a coaxial connection to a base station simulator or non-radiating load there may still be RF leakage from the WD, which may interfere with the desired measurement. Pre-measurement checks should be made to avoid this possibility. All measurements shall be done with the WD operating on battery power with an appropriate normal speech audio signal input level given in Table 7.1. If the device display can be turned off during a phone call then that may be done during the measurement as well. Measurements shall be performed at two locations specified in A.3, with the correct probe orientation for a particular location, in a multistage sequence by first measuring the field intensity of the desired T-Coil signal (ABM1) that is useful to a hearing aid T-Coil. The undesired magnetic components (ABM2) must be measured at the same location as the desired ABM or T-Coil signal (ABM1), and the ratio of desired to undesired ABM signals must be calculated. For the perpendicular field location, only the ABM1 frequency response shall be determined in a third measurement stage. The flow chart in Figure 7.3 illustrates this three-stage, two orientation process. 1 2 The following steps summarize the basic test flow for determining ABM1 and ABM2 . These steps assume that a sine wave or narrowband 1/3 octave signal can be used for the measurement of ABM1. a. A validation of the test setup and instrumentation may be performed using a TMFS or Helmholtz coil. Measure the emissions and confirm that they are within the specified tolerance. b. Position the WD in the test setup and connect the WD RF connector to a base station simulator or a non- radiating load as shown in Figure 7.1 or Figure 7.2. Confirm that equipment that requires calibration has been calibrated, and that the noise level meets the requirements given in 7.3.1. c. The drive level to the WD is set such that the reference input level specified in Table 7.1 is input to the base station simulator (or manufacturer’s test mode equivalent) in the 1 kHz, 1/3 octave band. This drive level shall be used for the T-Coil signal test (ABM1) at f = 1 kHz. Either a sine wave at 1025 Hz or a voice- like signal, band-limited to the 1 kHz 1/3 octave, as defined in 7.4.2, shall be used for the reference audio signal. If interference is found at 1025 Hz an alternative nearby reference audio signal frequency may be used.46 The same drive level will be used for the ABM1 frequency response measurements at each 1/3 octave band center frequency. The WD volume control may be set at any level up to maximum, provided that a signal at any frequency at maximum modulation would not result in clipping or signal overload. d. Determine the magnetic measurement locations for the WD device (A.3), if not already specified by the manufacturer, as described in 7.4.4.1.1 and 7.4.4.2. 1 Audio Band Magnetic signal - desired (ABM1): Measured quantity of the desired magnetic signal 2 Audio Band Magnetic signal - undesired (ABM2): Measured quantity of the undesired magnetic signal, such as interference from battery current and similar non-signal elements.

Report No.: 15I20402-S2D Issue Date: 5/4/2015 e. At each measurement location, measure and record the desired T-Coil magnetic signals (ABM1 at fi) as described in 7.4.4.2 in each individual ISO 266-1975 R10 standard 1/3 octave band. The desired audio band input frequency (fi) shall be centered in each 1/3 octave band maintaining the same drive level as determined in item c) and the reading taken for that band. Equivalent methods of determining the frequency response may also be employed, such as fast Fourier transform (FFT) analysis using noise excitation or input–output comparison using simulated speech. The full-band integrated or half-band integrated probe output, as specified in D.9, may be used, as long as the appropriate calibration curve is applied to the measured result, so as to yield an accurate measurement of the field magnitude. (The resulting measurement shall be an accurate measurement in dB A/m.) All measurements of the desired signal shall be shown to be of the desired signal and not of an undesired signal. This may be shown by turning the desired signal ON and OFF with the probe measuring the same location. If the scanning method is used the scans shall show that all measurement points selected for the ABM1 measurement meet the ambient and test system noise criteria in 7.3.1. f. At the measurement location for each orientation, measure and record the undesired broadband audio magnetic signal (ABM2) as specified in 7.4.4.4 with no audio signal applied (or digital zero applied, if appropriate) using A-weighting and the half-band integrator. Calculate the ratio of the desired to undesired signal strength (i.e., signal quality). g. Obtain the data from the postprocessor, SEMCAD, and determine the category that properly classifies the signal quality based on Table 8.5.

Audio Level and Gain Measurements Establish a call and obtain the 1 kHz speech output signal at 3.14 dBm0 from the CMU200 using the Network Bitstream “Decoder Cal.” Perform a measurement job to measure the RMS Coil Signal. Note the voltage level and calculate the desired level for GSM/W-CDMA and CDMA, which are, according to ANSI C63.19-2011 Section 7.4.2.1, -16 dBm0 and -18 dBm0 respectively. To determine the appropriate audio level, use the following equations, where x dBm0 is the measured RMS Coil Signal: GSM/W-CDMA Audio Level(-16 dBm0) = ((-16 dBm0) - (3.14 dBm0)) + x dBv Audio Signal Signal Measured (dBm0) Type Audio Level 3.14 -2.54 1 kHz sine -16 -21.68 Change the Network Bitstream from “Decoder Cal” to “Encoder Cal.” Similarly, run a measurement job with the “Encoder Cal” codec active and set the Gain in the measurement job to 10. Note the RMS Coil signal. To calculate the gain, the following equation was used, where y dBm0 is the measured RMS Coil Signal for the “Encoder Cal” measurement: GSM/W-CDMA Gain(-16 dBm0) = 10((Audio Lev el-16 dBm0 – y dBm0) / 20) * 10 Audio Signal Signal Measured Measured Calculated (dBm0) Type Audio Level Coil Signal Gain -16 1 kHz sine -21.68 -19.34 7.64 Finally, to determine the required gain for testing, we multiply the resultant gain with the required gain to achieve an approximate level of a 1 kHz sine signal.

When the gain is set to 64.79, the Audio Level measured is -21.81 dBV. The gain was manually adjusted until the Audio Level matched the original. The gain used for this project is 65.76. VoLTE No correction gain factors were measured for VoLTE due to the Rohde & Schwarz CMW500, Serial No. 125236, hosting a calibrated audio board. The gains used to measure VoLTE are set to100.

Report No.: 15I20402-S2D Issue Date: 5/4/2015 8. T-coil Measurement Criteria 8.1. Frequency Response The frequency response of the axial component of the magnetic field, measured in 1/3 octave bands, shall follow the response curve, over the frequency range 300 Hz to 3000 Hz. Figure 8.1 and Figure 8.2 provide the boundaries for the specified frequency. These response curves are for true field strength measurements of the T-Coil signal. Thus the 6 dB/octave probe response has been corrected from the raw readings. Page 13 of 20 UL Verification Services Inc. Doc.

Report No.: 15I20402-S2D Issue Date: 5/4/2015 8.2. Signal to Noise This specifies the signal-to-noise quality requirement for the intended T-Coil signal from a WD. The worst signal to noise of the two T-Coil signal measurements, as determined in Clause 7, shall be used to determine the T-Coil mode category per Table 8.5. Only the RF immunity of the hearing aid is measured in T-Coil mode. It is assumed that a hearing aid can have no immunity to an interference signal in the audio band, which is the intended reception band for this mode. So, the only criterion that can be measured is the RF immunity in T-Coil Mode. This is measured using the same procedure as for the audio coupling mode and at the same levels as specified in 6.4.
