System Description
H171804E_14_001 31 / 86
Signals enter and leave the coils of  the probe via connectors  which are clearly  labeled  and
located at the base of the probe. The same cable is used to carry the signal to and from the
probe.  Each  probe  has  an  inner  coil  (the  observe  coil).  This  coil  is  located  closest  to  the
sample  volume  to  maximize  sensitivity.  The  color  coding  of  the  inner  coil  BNC  follows  a
simple rule. It always has the same color as the rectangular strip located directly above the
BNC connectors. The following figure shows the labeling of a multinuclear probe. In this case
the broadband coil is the inner coil.
