Verification and Service Information
Performing a Verification Check of the Agilent 11982A
If the Agilent 11982A verification check fails
If the Agilent 11982A does not pass the verification check, you should recheck
what was being done when the problem occurred. A few minutes spent per-
forming some simple checks may save waiting for your instrument to be
repaired. Before calling Agilent Technologies or returning the unit for service,
please make the following checks:
1
Is the rear-panel voltage selector switch set correctly?
2
Is the line fuse good?
3
Does the line socket have power?
4
Is the unit plugged in to the proper ac power source?
5
Is the unit turned on? Check that the green light-emitting diode (LED) next to
the line switch is on, indicating that the power supply is on.
6
If other equipment, cables, and connectors are being used with the
Agilent 11982A, are they connected properly and operating correctly?
7
Review the procedure for the test being performed when the problem
appeared. Are all the settings correct?
8
Are the connectors clean? See
“Cleaning Connections for Accurate
for more information about cleaning the
connectors.
If the Agilent 11982A still fails, you have two options:
• Return the lightwave converter to Agilent Technologies for repair; if the light-
wave converter is still under warranty or is covered by an Agilent Technologies
maintenance contract, it will be repaired under the terms of the warranty or
plan (the warranty is at the front of this manual). If the lightwave converter is
no longer under warranty or is not covered by an Agilent Technologies mainte-
nance plan, Agilent Technologies will notify you of the cost of the repair after
examining the unit. See
“Returning the Instrument for Service” on page 4-4
for
more information.
• Repair it yourself. See
“Service Information” on page 4-8
