3.1 Hardware Test Connection

Perform the following steps for hardware test connection:
  1. Remove antenna matching components and solder RF coaxial cable on RF test point.
    Figure 3-1. RF Coaxial Cable Solder Test Connection on RF Test Point
  2. Refer to the following figure. The test mode connection is described as below:
    1. Connect the test interface of IS2083BM DUT (ADAP_IN, VBAT, GND, HCI_TX, HCI_RX and P3_4) to Edgar III board (USB to UART Converter Board) (5V, BAT, GND, HTX, HRX and P2_0).
    2. Edgar III connects to PC USB port and DUT connect to RF tester.
    3. Set the P2_0 of SW1 to ON on Edgar III (P3_4 of DUT pulled to low).
    Note: Refer to Appendix A: Edgar III Circuit. Contact Microchip sales or an FAE for Edgar III boards.

  3. Use the ISRT tool to configure RF test parameter.
  4. Test with RF equipment and verify RF Tx/Rx performance.
