Hello.
I'm using AC power entry module filter (http://www.mouser.com/Search/Produc...irtualkey69300000virtualkey693-DD12.4111.1111, DD12.4111.1111, Schurter) to construct the Faraday cage to protect circuit against strong EM wave during gas discharge experiment.
So far, the module is inserted to the cage with insulator such that ground of the module (so signal ground of the circuit) is not directly connected to the Faraday cage as intended for the circuit not to be affected by possible fluctuated voltage of the cage.
However, I read some article which seems suggest that the signal reference of the circuit and corresponding shield are to be at the same ground. Yeah maybe in this scheme, voltage of the cage and circuit's ground are the same so no current can induces between them but...Is it really good idea for strong EMI environment? If so, why? My vision is shaking between original thought and this...new finding.
Please give me clear view of shielding.
Thanks!
