l
For high frequency disturbances where high bandwidth measurement is
not required, the measurement bandwidth can be reduced by using the
lowpass filter of the acquisition card.
l
If unshielded cables are used, keep them as close together as possible, i.e.
position them next to each other (to keep the loop small).
l
Make sure that measurement cables that are used for measuring high
dynamic or distorting signals are not closely positioned to measurement
cables used for measuring small sensitive signals.
