Repair and replacement information for the 8472B crystal detector are given
below. For additional maintenance information, refer to “Service and
Support” on page v for the nearest Agilent Technologies Sales and Service
office.
The detectors have no internal adjustments.
Replaceable Parts Part numbers for replaceable parts are given in Table 2. To order a
replacement part, address your order or inquiry to the nearest Agilent

Detector Element
Replacement
The detector element assembly includes only a detector element. All other
internal parts are to be retained for re-use in the detector.
Read the following precautions carefully before performing any operation
with the detector element when it is out of either the housing or the detector
element shipping container.
CAUTION
• Before installing the diode into the mount, touch the exposed metal on
the mount with your hand to discharge static electricity.
• When handing the diode to another person, first touch hands to ensure
that there is no difference in static electricity potential between you.
• Ohmmeters should not be used to measure forward- and back-resistance
since it is easy to damage these diodes. The ohmmeter’s open-circuit
voltages and short-circuit currents may cause problems.
Parts mentioned in the following procedure are identified in Figures 2 and 3
on page 10.
1. Remove the female BNC connector and compression spring from inside
of the connector cap.
2. Remove the connector cap from the body. Use a pair of pliers with
plastic jaws or protect the body with heavy paper or tape.
