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.
