  The use of Printed Circuit Boards (PCBs) for the inductive pick-up windings
of rotating coil probes has made the construction of these precision magnetic
measurement devices much more accessible. This paper discusses the design
details for PCBs which on each layer of the board provide for simultaneous
analog bucking (suppression) of dipole, quadrupole, and sextupole field
components so as to more accurately measure the higher order harmonic fields in
sextupole magnets. Techniques to generate designs are discussed, as well as
trade-offs to optimize sensitivity. Examples of recent sextupole PCBs and their
performance are given.
