PCB-level EMI checking with PollEx DFE

N_Matsukawa

I was told by a Japanese distributor that Pollex cannot calculate the PCB current of analog signals. Looking at the top right of Page42,
the difference in radiation noise due to the presence or absence of a GND slit is shown.
In the PCB on the top left of Page42, it appears that the analog GND and digital GND are probably separated.
Normally, this method is used to prevent analog noise from affecting digital circuits.
However, since Pollex cannot calculate the PCB current of analog signals,
I think it is not possible to simulate radiation noise due to a GND slit.
