User’s Manual 5
1.4 CE Compliance
Equipment is generally divided into two classes.
These limits apply over the range of 30–230 MHz. The limits are 7 dB higher for frequen-
cies above 230 MHz. Although the test range goes to 1 GHz, the emissions from Rabbit-
based systems at frequencies above 300 MHz are generally well below background noise
levels.
The BL2000 single-board computer has been tested and was found to
be in conformity with the following applicable immunity and emission
standards. The BL2010, BL2020, and BL2030 single-board computers
are also CE qualified as they are sub-versions of the BL2000 single-
board computer. Boards that are CE-compliant have the CE mark.
NOTE: Earlier versions of the BL2000 sold before 2003 that do not have the CE mark
are not CE-compliant.
Immunity
The BL2000 series of single-board computers meets the following EN55024/1998 immu-
nity standards.
• EN61000-4-3 (Radiated Immunity)
• EN61000-4-4 (EFT)
• EN61000-4-6 (Conducted Immunity)
Additional shielding or filtering may be required for a heavy industrial environment.
Emissions
The BL2000 series of single-board computers meets the following emission standards
using the enhanced-EMI PCB, Part# 175-0224 Rev. A, and the 668-0003 Rev. A Rabbit
2000 microprocessor.
• EN55022:1998 Class B
• FCC Part 15 Class B
Your results may vary, depending on your application, so additional shielding or filtering
may be needed to maintain the Class B emission qualification.
CLASS A CLASS B
Digital equipment meant for light industrial use Digital equipment meant for home use
Less restrictive emissions requirement:
less than 40 dB µV/m at 10 m
(40 dB relative to 1 µV/m) or 300 µV/m
More restrictive emissions requirement:
30 dB µV/m at 10 m or 100 µV/m
