This report contains the Classic Bluetooth test results. Two samples were used in tests. The first sample had an integrated antenna and the other sample had an external antenna. Both modules were connected to their own evaluation boards. Conducted measurements were made with the sample having an external antenna. Measurements were made from the antenna connector (SMA). Classification of the device Fixed device Mobile Device (Human body distance > 20cm) Portable Device (Human body distance < 20cm) Modifications Incorporated in the EUT No modifications were applied to the EUT during testing Ratings and declarations Operating Frequency Range (OFR):2402 – 2480 MHz Channels:79 Channel separation:1 MHz Conducted power:7.56 dBm Transmission technique:FHSS Modulation:GFSK, π /4 DQPSK, 8DPSK Integrated antenna gain:3.29 dBi max External antenna gain:2.76 dBi Power Supply The following wall charger was used during the tests (supplied with 115 V/ 60 Hz). Charger: Manufacturer:PHIHONG Model:PSMR11R-120 Serial number:P73206336A1 Input voltage:100-240 VAC Rated current:0.3A max Rated frequency:50-60 Hz Output voltage:12 V DC Output current:0.84A MAX Reference number: 273079-2 Page 4 of 87 General remarks GENERAL REMARKS Disclaimer This test report is issued under SGS Fimko general terms of delivery (available on request and accessible at www.fi.sgs.com ).
