3. Leakage currents due to printed-circuit board contamination must be considered.
4. Use wide traces to reduce inductance and noise pick-up. Narrow traces more readily
5. Place a bypass capacitor of 10 nF close to the V

at the device side to the SA56004X GND pin and leave the shield at the remote end
unconnected to avoid ground loop currents. Also notice that the series resistance of
the cable may introduce measurement error; 1
