General Measurement Considerations
The instrument and experiment should be kept as far away as possible from any EMI sources.
Additional shielding of the instrument, experiment and test leads will often reduce EMI to an
acceptable level. In extreme cases, a specially constructed screen room may be required to suf-
ficiently attenuate the troublesome signal.
External filtering of the input signal path may be required. In some cases, a simple one-pole
filter may be sufficient. In more difficult situations, multiple notch or band-stop filters, tuned to
the offending frequency range, may be required. Connecting multiple capacitors of widely dif-
ferent values in parallel will maintain a low impedance across a wide frequency range. Keep in
mind, however, that such filtering may have detrimental effects (such as increased response
time) on the measurement.
