3.1 Hardware Test Connection
Perform the following steps for hardware test connection:
- Remove antenna matching components and solder RF coaxial cable on RF test point.
- Refer to the following
figure. The
test
mode connection is described as below:
- 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).
- Edgar III connects to PC USB port and DUT connect to RF tester.
- Set the P2_0 of SW1 to ON on Edgar III (P3_4 of DUT pulled to low).
Note: Refer to 8 Appendix A: Edgar III Circuit. Contact Microchip sales or an FAE for Edgar III boards. - Use the ISRT tool to configure RF test parameter.
- Test with RF equipment and verify RF Tx/Rx performance.
