Adding redundant grounds to various points in the total system often
helps. Please understand that ground loops and electromagnetic
interference can sometimes be challenging problems. In extreme cases,
the best approach is to patiently experiment by trying various
combinations of grounding connections. As a general rule, try to keep
ground wires short, make tight connections, avoid painted, coated, and
anodized surfaces when possible. Consider a
0
star ground" of wires
radiating from a single, central location, preferably connected to a
grounded metal table surface under the system.
In extreme cases, such as working with or around high powered pulsed
lasers or other high energy apparatus, it may be helpful to construct RFI
/ EMI shields or cages to contain the noise at its source, or to isolate the
detection system from the noise. In these cases, colleagues who are
working with similar apparatuses may be your best resource for noise
control suggestions.
