The Equipment Under Test (EUT) was the Model: Wireless CAN BridgeTransceiver. Radio-Noise Emissions tests were performed according to FCC Public Notice 54797, titled “Guidance on Measurement for Direct Sequence SST”. The measuring equipment conforms to ANSI C63.2 Specifications for Electromagnetic Noise and Field Strength Instrumentation. Testing was performed at National Certification Laboratory in Ellicott City, MD. Site description and site attenuation data have been placed on file with the FCC’s sampling and Measurements Branch. FCC acceptance was granted on May 26, 1993. 1.1 Summary: The Matric Limited Wireless CAN BridgeTransceiver complies with the FCC limits (15.247) for a Direct Sequence SST. FCC ID #: K5B-CANBRIDGE 3 2.0 Description of Equipment Under Test (EUT): The EUT features: 3.0 Test Program: This report contains measurement charts and data as evidence for the following tests performed: 1.(15.247b) Peak RF output power. 2. (15.247c) Field Strength of harmonics and spurious out-of-band emissions. 3. (15.247c) RF Antenna Conducted of harmonics and spurious out-of-band emissions. 4. (15.247a) 6 dB Emission Bandwidth. 5. (15.207) Power Line Conducted Emissions. 6.(15.247d) Power Spectral Density. Reverse Polarity SMA Antenna Connector per 15.203 +10 dBm Max. RF Output 2410.50 MHz Center Frequency 13.2 MHz 6 dB Emission Bandwidth Single Channel 1 Mbps Max. Data Rate (DBPSK) 4 inch Monopole External Antenna (2.5 dBi) FCC ID #: K5B-CANBRIDGE 4 4.0 Test Configuration: RF antenna output tests such as Bandwidth, Spurious/Harmonics, Power output, were taken with the transmitter antenna connector feeding directly into the spectrum analyzer via external 30 db attenuator, or into the Peak RF Power meter as appropriate. The analyzer’s internal attenuator was adjusted to prevent overloading of the front end. The transmitter is modulated at 1 Mbps which is the highest available data rate. Field strength measurements were taken with the transmitter feeding a 2.5 dBi monopole omni antenna aligned with the measurement horn antenna. No other antennas are provided with the EUT. Testing was performed at maximum RF power output. PEAK POWER TEST RESULTS Limit:1 watt (30 dBm) Condition:Transmitter is set to a single modulated channel at full RF power.

A 4 inch monopole antenna is attached to the transmitter via reverse polarity SMA connector. The transmitter is turned on and automatically begins transmission at full RF power output, once initialized. 6.0 Conducted Emissions Scheme: The EUT is placed on an 80 cm high X 1.5 m non-conductive table. Power to the RF modem is provided through a Solar Corporation 50 ohm/50 uH Line Impedance Stabilization Network bonded to a 2.2 X 2 meter horizontal ground plane, and a 2.2 X 2 meter vertical ground plane. The LISN has its AC input supplied from a filtered AC power source. A separate LISN provides AC power to the peripheral equipment. I/O cables are moved about to obtain maximum emissions. The 50 ohm output of the LISN is connected to the input of the spectrum analyzer and emissions in the frequency range of 450 kHz to 30 MHz are searched. The detector function is set to Quasi-Peak and the resolution bandwidth is set at 9 kHz, with all post detector filtering no less than 10 times the resolution bandwidth for final measurements. All emissions within 20…
