1 Introduction The QCA99xx with VIVETM 802.11ac technology is a highly integrated WLAN System-on-Chip (SoC) for 5 GHz 802.11ac or 2.4/5 GHz 802.11n WLAN applications. The QCA9984/ QCA9994/ QCA9886 dual-synthesizer WLAN radio supports 160 MHz and 80+80 MHz, while the QCA9980/QCA9990 single-synthesizer WLAN radio supports 80 MHz. The 160 MHz or 80+80 MHz signal comes from two separate RF ports, with one 80 MHz coming from chain 1 the other from chain 2. A cable connection for the single stream test uses a 4-to-1 combiner between 4 RF connectors on CUS239 and the single RF test port of the tester. The QCA9886 only supports a 2x2 RF test port; its cable connection for a single stream test uses a 2-to-1 combiner between two RF connectors on the QCA9886 and a single RF test port on the tester. Two testers are needed for the 2-stream test. Use a 2-to-1 combiner to combine the 2 RF ports for 1- stream and connect to one tester. Use another 2-to-1 combiner to combine the remaining two RF ports for the second stream, and then connect to the second tester. Figure 1-1 shows the DUT in the test setup: CUS239 PCIE module, PCIE adapter board for 3.3V/5V power source and PCIE BUS.

Use QDART to Test QCA99XX Application Note Introduction To get better EVM for 80+80MHz, Litepoint suggests that the correct connection should be set up as shown in Figure 1-3: Figure 1-3 QCA9984: Wi-Fi module connection with IQxel160 Information in this document can be used to convert the QCA9980/QCA9990 (80 MHz) test setup to the QCA9984/QCA9994/QCA9886 (160 MHz or 80+80 MHz) test setup. The DUT is CUS239 PCIE module.

2 Changing the QCA9980/QCA9990 test setup to QCA9984/QCA9994 This section describes the steps to change the QCA9980/QCA9990 test setup to QCA9984/QCA9994. 2.1 Prepare the PC Change the PC to test mode: 1. Right-click on the Command prompt, then click Run as administrator. 2. In the Command prompt window, enter the command Bcdedit.exe -set TESTSIGNING ON 3. Close the Command prompt window. 4. Restart the computer. After restart, Test Mode should be displayed in the bottom right of the screen. 2.2 Prepare the tester The Wi-Fi RF test vendors (Litepoint, National Instrument, Anritsu, and Keysight) can be contacted directly for the latest status about the capability of their Wi-Fi tester and the technical support to have tester configured correctly for 802.11AC 160 MHz. This section uses Litepoint IQxel as an example for QCA9984/QCA9886 Wi-Fi test. Change tester from Litepoint IQxel_80Mhz to Litepoint IQxel_160MHz. Upgrade Litepoint IQxel_160MHz with the latest firmware. Use Chrome browser to access IQxel web-based setup interface, such as 192.168.100.254. (Other browsers like IE and Firefox might find it difficult to load the library file.) Use these instructions to update library and upload new waveforms: 1. Clean old library. a. Go to Tools > SCPI Console and type command: TFC:LIBR:MEM:LIBR:USER:PREL:LIST? If response is “none”, it means no previous installed library. If response shows a name of library, uninstall it before installing a new one. b. To uninstall old library, go to Tools > SCPI Console and type command: TFC:LIBR:UPR:UNIN:ALL. c. Power cycle tester. After power cycle, use command TFC:LIBR:MEM:LIBR:USER:PREL:LIST? to make sure no library is installed. 80-Y8050-46 Rev.

Open tester’s GUI in browser and go to File > File Browser > LIBRARY > Upload. Choose LitePoint_QTI_Scpi_Library.js as shown in Figure 4. Figure 4 Upload library file 3. Install library a. Go to Tools > SCPI Console In SCPI Console, type command: TFC:LIBR:UPR:INST:ENCR “LitePoint_QTI_Scpi_Library.js” b. Power cycle tester 4. Check if library is installed successfully. a. Go to Tools > SCPI Console. 5. In the SCPI Console, type command: TFC:LIBR:MEM:LIBR:USER:PREL:LIST? a. If response is “LITEPONT QTI SCPI LIBRARY”, the library is installed successfully. b. In SCPI Console, type command LITEpoint:LIBRary:VERSion? to make sure library version is the one that you installed. 80-Y8050-46 Rev.

Go to File > File Browser > user > Upload and choose all waveforms in iqvsg folder in the package. This step will upload selected waveforms to the user folder in tester’s memory. 2.3 Set the DUT with the correct driver DUT can be a Wi-Fi module plugged in PC with Windows OS or AP (Access Point) with Linux OS. 2.3.1 DUT with FTM Windows driver Delete old QCA9980/QCA9990 FTM Window driver to install QCA9984/QCA9994 FTM Windows driver. Before installing QCA9984/QCA9994 driver and QCA9980/QCA9990 driver has been installed already. 1. Plug QCA9980/QCA9990 card, go to Device Manager > Network adapter > QC99xx property and click uninstall. 2. From command prompt, regedit go to HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet\services, then delete qcamain entry, reboot the system. 3. Install FTM driver. 4. Copy firmware and BDF. Copy utf_AR9984.bin, utf_AR9984_codeswap.bin, otp_AR9984.bin and fakeBoadData_AR9984.bin to C:\Windows\System32\drivers. 5. Plug QCA9984/QCA9994 card. NOTE: For any Qualcomm® certificate issue, copy \FTM-Driver\Qca9900x64.sys to C:\Windows\System32\drivers unplug and re-plug. 2.3.2 DUT with Linux driver IPQ8064.ILQ.3.0 release will include driver for QCA9984 driver. For example, AP161 has QCA9984-based reference boards CUS239/CUS260 plugged in. Firmware and BDF for Wi-Fi is located under /lib/firmware/QCA9984/hw.1 inside AP file system. QCA9886.ILQ.1.0 release will include driver for QCA9886 driver. For example, AP147/AP151/AP152 has QCA9886 mounted on board. Firmware and BDF for Wi-Fi is located under /lib/firmware/QCA9888/hw.1 inside AP file system. 80-Y8050-46 Rev.
