4 Measurement Setup and Procedure
4.1 Test Channel
According to ANSI C63.10-2013 chapter 5.6.1 Table 4 requirement, the lowest, middle, and highest channels in the frequency range of device operation were selected for testing. The detailed frequency points are as follows:
- Lowest channel: Channel No. 0, Frequency 2402 MHz
- Middle channel: Channel No. 20, Frequency 2442 MHz
- Highest channel: Channel No. 39, Frequency 2480 MHz
4.2 Test Setup
- Conducted emission measurement: The setup involves the EUT connected to a Line Impedance Stabilization Network (LISN) and a test receiver. The LISN provides a 50ohm/50uH coupling impedance. The diagram shows the EUT, LISN, and connections to the test equipment, placed on a non-conductive table above a conducting ground plane.
- Radiated emission measurement:
- Below 1GHz (3m SAC): The EUT is placed on a rotating table 0.8m above the ground in a 3m semi-anechoic chamber. The measurement distance from the EUT to the receiving antenna is 3m. The setup includes the EUT, turntable, ground reference plane, pre-amplifier, test receiver, and optical cable controller.
- Above 1GHz (3m FAR): The setup is similar to below 1GHz but conducted in a 3m fully anechoic room, with the EUT on a rotating table 1.5m above the ground.
- Conducted test method: The BLE antenna port of the EUT is connected to the test port of the test system through an RF cable. The EUT is kept in continuous transmission mode and tested in all modulation modes. The setup involves signal generators, spectrum analyzers, and other test equipment connected to the EUT.
4.3 Test Procedure
The test procedures followed are detailed for Conducted Emission, Radiated Emission (below 1GHz and above 1GHz), and Conducted Test Method, involving specific steps for setup, operation, and data acquisition using test software.
