Status Listings
Overview
Overview
This document describes the status listings of the HP 86140 series optical
spectrum analyzers. Status conditions for the optical spectrum analyzer are
grouped into categories.
Error
Indicates the instrument is malfunctioning. Measurement accuracy is probably
affected. Errors can be caused by either a hardware or a firmware problem.
The instrument requires repair at a Hewlett-Packard service center.
Status error
Indicates an internal hardware function is unavailable or not operating within
specifications. This is usually a temporary problem, such as a temperature
control loop being unsettled. Status errors cannot be cleared by the user.
When the condition causing the error is corrected the error will go away.
Warning
A warning is displayed when the optical spectrum analyzer cannot satisfy a
request from the user. Parameter entries that are out of range, illegal or unrec-
ognized remote commands or missing hardware options can cause a warning
to be displayed. A warning can be displayed if a requested measurement, for
example AutoMeasure, cannot be performed due to a missing input signal.
UNCAL
This message alerts the user the requested instrument setup can cause an
invalid measurement. For example, manually setting the sweep time to a value
that is too fast for other instrument settings.
Notice
A user alert indicating something in the state of the instrument has changed.
For example, if the user specifies a particular value for the current duty cycle,
a notice will be displayed when the optical spectrum analyzer modifies the
pulse width .
