On my last E-mail, I goofed by looking at the wrong data in some EMCAD1 predictions. The 39 dBuv figure was for a very high impedance line, NOT a 50-Ohm line. The analysis I ment to reference used a 66 MHz clock (not 33 MHz) and failed CISPR Class A at the fundamental and second harmonic only (i.e., >30 dBuv). All other comments remain the same. The analyzed trace was a one inch, 50-Ohm microstrip with 1 ns rise and fall times. The predicted 66 MHz emission level at 30 meters was 34.5 dBuv. Sorry for the error. Mike Michael L.
