5.4 External Interference

────────────────────────────────────────────────────

Fitting an anti-interference ferrite core on the power cord

Pass the power cord through a commercially available anti-interference
ferrite core, and fix it on the power cord as close as possible to the AC
power inlet of the 3522-50 unit, so as to suppress noise from the power
supply line. Further benefit can often be obtained by fitting another anti-
interference ferrite core on to the power cord at its other end, as close as
possible to the plug which connects to the power supply outlet.
Moreover, if the internal diameter of the ferrite core allows, winding the
power cord several times around the ferrite core may further reduce the
amount of noise. Various types of such anti-interference ferrite cores or
ferrite beads are readily available in the market from specialist
manufacturers.
