2.1 Equipment Under Test (EUT) Information

The following information has been supplied by the client:

• Product Name: A700x Series Devices (A710x, 720x, 730x)
• Model Number: TAP1010-02, TAP1020-02, TAP1030-02
• Serial Number: Engineering Sample
• FCC ID: HD5-TAP1000-02
• IC ID: 1693B-TAP100002

2.2 Product Description

The EUT is a handheld communication device consisting of the Laird SU60-SIPT WLAN 2.4/5 GHz and BLE/BT module. The EUT also contains the NXP PN7150BOHN/C110xx NFC radio. The EUT was powered by a 3.7 VDC battery. The WLAN operates in SISO mode only.

The EUT has three different models:

• A710x - Contains the basic wireless functionality
• A720x - Contains an end cap with two external proprietary connectors that add on the ability to connect a wired headset and a peripheral device such as a printer or scanner.
• A730x - Contains an imager end cap that adds scanning functionality.

All models use identical radios and circuit boards in the "base unit" and the different A700x versions add additional (non-radio) capabilities through different, factory configurable "end caps". All conducted testing was completed on the A710x model. Radiated measurements completed for all three models.

2.3 Modifications Incorporated for Compliance

None noted at time of test

2.4 Deviations and Exclusions from Test Specifications

None noted at time of test

2.5 Channels and Data Rates

2.6 Radio Programming

The WLAN radios were programmed using the Laird Regulatory Tool v 9.32.0.6. BLE and BT radios were programmed using default HCI commands via the windows command prompt. The NFC radio was programmed using Honeywell's CBOB program V1.0.

2.7 Simultaneous Transmission

The EUT radio combinations capable of simultaneous transmission are:

• WLAN 5 GHz + BT/BLE + NFC
• WLAN 2.4 GHz + NFC

2.8 Antennas

The device contains three antennas:

• Custom dual band PCB inverted F type antenna with peak gains: +4.7 dBi in 2400-2484 MHz, +6.4 dBi in 5150-5350 MHz, +6.9 dBi in 5470-5725 MHz, +7.3 dBi in 5725-5850 MHz.
• Custom PCB inverted F type antenna with a peak gain of +0.2 dBi for the BT/BLE radios.
• Flex circuit magnetic loop antenna, P/N 1002403 for the NFC radio.

4 Uncertainty Summary

The calculated measurement uncertainty represents an expanded uncertainty expressed at approximately the 95% confidence level, using a coverage factor of k = 2.

5 Test Data

5.1 Radiated Emissions

The frequency spectrum is investigated for intentional and / or unintentional signals emanating from the EUT by use of a standardized test site and measurement antenna.

The antenna, cable, pre-amp, and other necessary measurement system correction factors are loaded onto the EMI receiver / spectrum analyzer when the measurements are performed, allowing the data to be gathered and reported as corrected values.

The maximum emissions from the EUT are determined by turn-table azimuth rotation (360°) and scanning of the measurement antenna. Maximized levels are noted at degree values of azimuth, measurement antenna height, and measurement antenna polarity.

Example Calculations

Measurement (dBμV) + Cable factor (dB) + Other (dB) + Antenna Factor (dB/m) = Corrected Reading (dBμV/m)

Margin (dB) = Limit (dBμV/m) - Corrected Reading (dBμV/m)

Example at 4000 MHz: Reading = 40 dBμV + 3.4 dB + 0.9 dB + 6.5 dB/m = 50.8 dBμV/m. Average Limit = 20 log (500) = 54 dBμV/m. Margin = 54 dBμV/m - 50.8 dBμV/m = 3.2 dB.
