12.1.1.1 Test Procedure for Ensuring Compliance

The following test must be performed both at the design verification stage and in production to ensure compliance.

1. Initiate Continuous Transmission in the appropriate modulation mode from the device that is, 868.3 MHz; BPSK-20 for European band and 914 MHz; BPSK-ALT-40 for North American band.
2. Verify RF power through conducted measurement at junction between L106 and L105.
3. Remove L106 and R115 to isolate the antenna path from the measurement point. It is recommended that the measured TX power be within the data sheet specification for the Transmit output power. For good measurement, it is recommended that there be a firm connection between the copper core of the coaxial cable and the measurement point. Ensure the copper shield of the coaxial cable is firmly connected to the GND of the PCB.
