CYBLE-022001-00 – Conducted Pre-Compliance tests – FCC/IC and ETSI Summary The CYBLE-022001-00 module passes all the requirements stated in the relevant sections of both FCC Part 15, IC (RSS210 Issue 8) and ETSI EN-300-328. The detailed list of all conducted tests, regulatory limits and the results are documented below. Test Setup The internal pre-compliance tests are done in a conducted setup. For making a conducted setup, components C11 and L2 (antenna matching network) are removed from the module and a coaxial cable is connected on the radio side pad of L2 (highlighted in red in the following picture). Before performing the tests, the attenuation caused by the open ended cable and coaxial cable are measured and the attenuation value is compensated in the CBT scripts for all the tests done. Page 1 of 32 List of tests done FCC/IC treats BLE as a Digital Transmission System. All the tests are done as per FCC guidance for Performing Compliance Measurements on Digital Transmission Systems (DTS). The following is the list of tests done for FCC Part-15 and IC (RSS210 Issue 8): 1. 2. 3. 4. 5. 6. DTS bandwidth Transmission Duty Cycle Fundamental emission output power Maximum power spectral density level in the fundamental emission Out of Band Spurious Measurements Band Edge Measurements For ETSI, Bluetooth SIG considers BLE as Equipment using other types of wide band modulation (e.g. DSSS, OFDM, etc.). The following tests are covered for the ETSI (EN 300-328): 1. RF output power 2. Power Spectral Density 3. Occupied Channel Bandwidth 4. Transmitter unwanted emissions in the out-of-band domain 5. Transmitter unwanted emissions in the spurious domain 6. Receiver spurious emissions Page 2 of 32 FCC test results DTS Bandwidth: Measurement was done based on option 2 of FCC guidance.
