Spectrum Analyzer Error Messages
Error Messages
The spectrum analyzer can generate various messages that appear on its screen during
operation to indicate a problem.
There are three types of messages: hardware error messages (H), user-created error messages
(U), and informational messages (M).
H
Hardware error messages indicate the spectrum analyzer hardware is probably broken. Refer
to Chapter 8 in the HP 8590 E-Series and
L-Series

n User-created error messages appear when the spectrum analyzer is used incorrectly. They are
usually generated during remote operation (entering programming commands using either a

w
Informational messages provide information indicating the spectrum analyzer’s progress
within a specific procedure.
