Cable Length and Noise Considerations
Cable Length and Noise Considerations
Cable should not exceed one 3’ (one meter) to avoid electrical noise to be captured by the
wiring. A ferrite core filter must be used for length beyond 2’ (60 cm). For longer cable
length use an oscilloscope to verify signal integrity on each of the pulse channels and on
the power supply.
