Equipment Function
The EUT is a GPS receiver and display unit offering reception and display of location,
navigation, and other information for the user. The GPS design offers use as a hand-held or
portable configuration for use in navigational and data tracking applications. The design
incorporates transmitter circuitry for wireless communications with compatible equipment.
The low power transmitter provides operation and 2402-2480 MHz frequency band. The
design provides wireless communications in two modes including ANT and Bluetooth® Low
Energy (BLE) providing wireless interface capabilities with compatible equipment. The
product operates from internal rechargeable battery and requires recharge using external direct
current power sources as documented in this report. The design offers no other interface
options than those presented below in the configuration diagram. The design utilizes internal
fixed antenna system and offers no provision for antenna replacement or modification. Two
samples were provided for testing, one representative of production design, and the other
modified for testing purposes replacing integral antenna with RF connection port. The test
samples were provided with test software which provided the ability to enable transmitter
functions on defined modes and channels. The antenna modification provided the ability to
connect test equipment to the temporary antenna port for antenna port conducted emission
testing. The EUT was arranged as described by the manufacturer emulating typical user
configurations for testing purposes. For testing purposes, the EUT was powered from freshly
charged internal battery or external power options and configured to operate in available
modes. As requested by the manufacturer and required by regulations, the equipment was
tested for emissions compliance using the available configurations with the worst-case data
presented. The test software enabled the transmitter to operate near 100% duty cycle for
testing purposes. The production product will not operate at these high duty cycles. This
report documents compliance testing and results for applicable product modes of operation.
Test results in this report relate only to the products described in this report.
