EM1500 Specifications
A.3 EM1500 EMI / EMC Information
This section describes the immunity and emissions standards met by the EM1500. Design guidelines are
given to help developers incorporate the EM1500 into an application while staying CE compliant.
Equipment is generally divided into two classes.
These limits apply over the range of 30–230 MHz. The limits are 7 dB higher for frequencies 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.
A.3.1 CE Compliance
The EM1500 has been tested and was found to be in conformity with the following applicable immunity
and emission standards. EM1500s that are CE-compliant have a label with the CE mark on the front panel
of the unit, similar to that shown in

Immunity
The EM1500 meets the following EN55024/1998 immunity standards.
• EN61000-4-2 (Electrostatic Discharge)
• 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.
