In the event of diode burnout, field-replaceable detector
elements are available for economical customer repair.
The critical components are supplied (and tested) as an
integrated unit, with the mount playing only a minor role in
determining frequency response and SWR. The following
table lists field-replaceable detector modules that have
been tested to their respective specifications.
