Check the Basics
Check the Basics
In general, a problem can be caused by a hardware failure, a software
error, or a user error. Often problems may be solved by repeating what
was being done when the problem occurred. A few minutes spent in
performing these simple checks may eliminate time spent waiting for
instrument repair.
❏ Check that the analyzer is plugged into the proper ac power source.
❏ Check that the line socket has power.
❏ Check that the rear-panel voltage selector switch is set correctly.
❏ Check that the line fuse is good.
❏ Check that the analyzer is turned on.
❏ Check that the other equipment, cables, and connectors are
connected properly and operating correctly.
❏ Check the equipment settings in the procedure that was being used
when the problem occurred.
❏ Check that the test being performed and the expected results are
within the specifications and capabilities of the analyzer. Refer to
the calibration guide for your instrument.
❏ Check the analyzer display for error messages. Refer to the 8590
E-Series and L-Series Spectrum Analyzers User's Guide or 8591C
Cable TV Analyzer User's Guide, Spectrum Analyzer Reference.
❏ Check operation by performing the verification procedures in the
calibration guide for your instrument. Record all results in the
Performance Test record.
If there is still a problem, refer to Chapter 4 in this book.
