MK8000 EVB Quick Start Guide 1. Overview FCC ID: 2A7T8MK8000UWBA This document provides a quick start guide on testing and evaluation of the MK8000 chipset [1] features and performance using the MK8000 evaluation kit. MK8000 evaluation kit has two operation modes --- standalone and MKTool mode.  Standalone mode o The EVB starts to work automatically once powered on. The measurement result is updated periodically in a Windows console through the serial port.

MK8000 EVB Quick Start Guide Figure 4 Tag connection 3.5 MKTool mode hardware setup The MK8000 EVB MKTool mode needs two MK8000 EVBs and Windows laptops with MKTool software installed. MKTool is a Windows application program developed by MKSEMI and used to configure the chip and the EVB, perform and control the MK8000 chipset evaluation. It has a GUI interface for configuration and results display. Both EVBs need to download the MKTool firmware to perform the test.

MK8000 EVB Quick Start Guide 4. Software setup This chapter provides an overview of software setup of MK8000 EVB. Software setup is needed when MKTool mode is used in the testing and evaluation. There is no need to program the MK8000 EVB if Standalone mode is used in the test and evaluation. 4.1 MK8000 Device Description File Installation MK8000 SDK supports Keil, IAR and GCC IDE platforms for code development and debugging.

MK8000 EVB Quick Start Guide Figure 6 MK8000 SDK package 4.3 Firmware download Before testing and evaluation, user needs to download the proper firmware into the MK8000 chipset. MKSEMI provides an application software, the ISPTool, to download the firmware. To download the firmware, user needs to connect the EVB to the laptop and get a proper COM port number in Windows Device Manager for this device and launch the ISPTool application.

Application examples This chapter provides an introduction of procedures for two basic tests:  Ranging and AoA  Power consumption 5.1 Ranging and AoA test At the beginning of test, the proper bin file should be downloaded to MK8000 EVBs. Get example project from the following locations then make the bin file or get bin file directly.   5.1.1 Standalone mode o project: “sdk_folder\boards\mk8000_dk\uwb_examples\aoa_loc” o bin file: “sdk_folder\boards\mk8000_dk\u

The console will show the measurement log as shown in Figure 10. The ranging measurement is based on Double-sided Two-way-Ranging protocol, and the angle measurement is based on Angle of Arrival (AoA) scheme.

MK8000 EVB Quick Start Guide 1. Open proper COM port number. Com port will be shown at left-bottom corner. 2. Click the “Ranging” Tab at the top of the GUI manual. 3. Select the “Tag” Role. 4. Click the “Restart” button to start the device as a Tag role in the measurement. Figure 11 also shows the steps of configuration. Figure 11 MKTool Mode Tag side configuration 5.1.2.2 Anchor configuration The Anchor is an MK8000 EVB which connects to 4-element linear array antenna.

Figure 15 shows the schematic of related portion. User can use a multimeter and J95 to perform a coarse test, and an oscilloscope and J95 to perform an accurate test. Figure 15 schematics associated with current measurement 5.2.

MK8000 EVB Quick Start Guide 5.2.2 Fine measurement of current consumption This test uses the following steps with an oscilloscope to measure the fine current consumption of MK8000 EVB. The current consumption is equal to the voltage measured by the scope / the resistance of R145 (default value 1Ohm) 1. Power off the MK8000 EVB 2. Leave the J95 at the disconnect state and short the J96 3. Connect the two pins of J95 to the oscilloscope and each pin connect to a channel 4. Power on the EVB by J105 6.
