APPENDIX A - EMC TEST RESULTS
The Merlin has been designed to cope with large EMC disturbances. This has been achieved by
constantly testing and improving fi ltering and layout techniques over many years. The Merlin
off ers superior R.F. fi ltering on all inputs, outputs and power supplies, when compared to
most competing products.
The Merlin not only meets CE noise requirements, but surpasses them in many tests. Further-
more, all testing was performed in plastic enclosures without shielded cabling.
