SLICE Grounding and Shielding Overview
Electromagnetic Interference (EMI), Radio Frequency Interference (RFI) and
Electrostatic Discharge (ESD) can seriously degrade the performance of
electronic equipment if not addressed. DTS SLICE systems contain protection

for EMI/RFI/ESD, however, many dynamic testing environments
(pyrotechnics, blast) are particularly noisy and require the utmost attention
to grounding and shielding practices. The following recommendations are
intended to maximize protection and keep systems functioning properly in
the harshest environments
the harshest environments.
Ground all DAS equipment, power supplies and sensor mounting fixtures
whenever possible. This is an extremely important step toward ensuring the
best performance from your SLICE system.
•
Always connect a cable from a good Earth ground to the test article, test fixture or
instrumented vehicle. Not only does this help divert potentially disruptive electrical
energy, it is also good safety practice. For remote testing applications, a metal ground
rod driven 3 ft into the soil can be an effective Earthing device.

•
Ground all SLICE enclosures to the test article or vehicle
•
Install ground cables between all SLICE Stacks and the test article or vehicle.
•
Install ground cables between electrically isolated test article/sensor mounting surfaces
and the SLICE Stacks.
