Date: October 28, 2015 American Certification Body, Inc. 6731 Whittier Avenue Suite C110 McLean, VA 22101 To Whom It May Concern: Regarding the USB1 FC Wi-Fi BLE adapter. Fluke is aware that classic Bluetooth is not an allowable mode of operation in all products that host the adapter. The classic Bluetooth mode (BR and EDR) will not be available in all Fluke test instrument host products that use the adapter. The host firmware that resides inside a Fluke test instrument limits the Bluetooth mode of operation to Bluetooth low energy only, the adapter will not operate or transmit without the firmware in the host, so Bluetooth low energy is the only mode of Bluetooth operation. .

The USB1 FC is a WiFi & BLE wireless to USB adapter to be used in test and measurement equipment such as the 1735 Energy Logger to communicate readings wirelessly. The adapter is placed inside the instrument and the instrument is left to record voltage and current over a period of time. The adapter will host the STM32 microcontroller along with the TI WL1831 radio module. The STM32 will act as a USB to SDIO and USB to UART bridge between the host Fluke product and the WL1831 radio module. The unit is powered via a 5V USB connector and utilizes a TDK chip antenna with Peak Gain in 2.4GHz band = 2.27 dBi The USB1 FC is intended for use only inside a Fluke test instrument and is not a general purpose adapter for use with a PC. It will not operate or transmit without the host firmware so it cannot be operated when connected to a PC The host firmware that resides inside a Fluke test instrument limits the BT mode of operation to BLE only. It will not operate or transmit without the host firmware so BLE is the only mode of BT operation. Microprocessor Number: ST Micro STM32F427IH6 Transceiver Number: TI WL1831MOD

Fluke Corporation Telephone Facsimile Email PO Box 9090 Everett WA 98206.9090 USA 425.347.6100 425.356.5108 http//www.fluke.com Date: August 11, 2015 To Whom It May Concern Regarding: Methods used for limiting WLAN transmit frequency range in the USB1 FC Wireless adapter The purpose of this letter is to describe the methods used to limit the operating frequency of the WLAN transmitter in the Fluke USB1 FC wireless adapter. The operating channels are limited to channels 1 through 11 the 2.4GHz ISM band for 20MHz channel bandwidth, 1 through 7 for 40MHz high channel bandwidth, and 5 through 11 for 40MHz low channel bandwidth. These channel limitation are enforced using the following methods: Restricted access to WLAN configuration tools: As the device is configured from the factory, it is impossible for any third party (users, installers, integrators, service personnel, etc.) to gain access to any parameters through the user interface which can configure the device to operate on WiFi channels 12, 13, or 14. Furthermore, Fluke provides no means for a third party to configure the device through an authorized software modification or by network configuration to allow the device to operate on WiFi channels 12, 13, or 14. The only known means to access to the parameters that configure access to WiFi channels 12, 13, or 14 is restricted through the use of an SSL cryptographic key, which is only provided to authorized personnel. Use of the Linux Central Regulatory Domain Agent (CRDA) to enforce FCC regulatory permissions: The host for the USB1 FC uses the Linux operating system, and implements CRDA to enforce FCC regulatory permissions. The wireless core driver (cfg80211) will only be allowed to initiate transmission on a given channel if the entire channel bandwidth is contained within the frequency range defined by the CRDA. For the USB1 FC, the allowed frequency range is coded in the firmware as a minimum 2402 MHz and a maximum of 2472 MHz. For each operating mode, cfg80211 will only enable channels that fall completely within this range, Tables 1-3 define the enabled and disabled channels for the 20 MHz (HT20), 40 MHz low , (HT40-) and 40 MHz high, (HT40+) operating modes Fluke Corporation Telephone Facsimile Email PO Box 9090 Everett WA 98206.9090 USA 425.347.6100 425.356.5108 http//www.fluke.com Fluke Corporation Telephone Facsimile Email PO Box 9090 Everett WA 98206.9090 USA 425.347.6100 425.356.5108 http//www.fluke.com A detailed description of the processing rules applied by the CRDA is available here: https://wireless.wiki.kernel.org/en/developers/regulatory/processing_rules Sincerely, James E.

Note: Bluetooth and WLAN radios do not transmit at the same time. Please refer to Appendix A for BT and WLAN Coexistence information. W66 N220 Commerce Court ● Cedarburg, WI 53012 ● www.lsr.com Typical application for the EUT W66 N220 Commerce Court ● Cedarburg, WI 53012 ● www.lsr.com Associated Antenna(s): The antenna used by the EUT is a TDK multilayer chip antenna, ANT016008LCD2442MA1 with a peak gain of 2.27 dBi. Statement of compliance: The Fluke USB1 FC WIFI-ADAPTER was evaluated against the SAR test exclusion threshold listed in KDB 447498 D01 General RF Exposure Guidance v05r02 for 10-g extremity at a distance of 5mm as well as RSS-102 Issue 5 for limb-worn at a distance of 15mm. W66 N220 Commerce Court ● Cedarburg, WI 53012 ● www.lsr.com Separation Distance: The EUT was evaluated against the SAR test exclusion threshold listed in KDB 447498 D01 General RF Exposure Guidance v05r02, section 4.3 (1). The EUT was found to be compliant with the SAR exclusion threshold, 10-g extremity, for 100MHz to 6000MHz. Note that the measured output power of the EUT is equivalent to the target output level. Frequency = 2.412GHz ERP (dBm) = 11.5dBm + 2.0 dBm (manufacturing tolerance) = 13.5dBm ERP (mW)= 22.4 milliwatt Minimum separation distance = 5mm [22.4mw/5mm]*[ √2.412GHz] = 4.48*1.55 =6.9 ≤ 7.5 When evaluated against RSS 102 issue 5 section 2.5, table 1: Frequency = 2.412GHz EIRP (dBm) = 11.5dBm + 2.3dBi + 2.0 dBm (manufacturing tolerance) = 15.8dBm ERP (mW)= 38.0 milliwatt Interpolating between 1900 and 2450 MHz for 2412 MHz at separation distance of 15 mm yields exemption limit of 15.2 mW Applying the limb-worn 10 gram value multiply by a factor of 2.5 = 15.2 *2.5 = 38 mW W66 N220 Commerce Court ● Cedarburg, WI 53012 ● www.lsr.com Scree…
