37
Transformer T101 (for a transformer isolated coupling circuit)
Transformer with correct specifications is selected (see Appendix C)
38
No filters or power supply transformers are in the coupling circuit path. If a ferrite bead is in the
coupling circuit path it is either common mode connected (see Chapter 6) or has been verified to be
<0.5
