Introduction
This chapter contains information about the power meter’s error messages. It
explains how to read the power meter’s error queue and lists all of the power
meter’s error messages and their probable causes.
When there is a hardware related problem, for example, a power sensor
overload, the error message is displayed on the status line at the top of the
display. In addition, the errors are also written to the error queue. If there are
any errors in the error queue, the front panel error annunciator is displayed
as shown in
Figure 4-1 .

Other errors can also be generated when the power meter is being
operated over the remote interface. These errors
also display the error annunciator and are writ-
ten to the error queue.
Error Annunciator Position
To read the error queue from the front panel, press:
•
, , , then use to scroll through
each error message.
To read the error queue from the remote interface, use the
SYSTem:ERRor?
command.
Error queue messages have the following format:
For example, –330, “Self-test Failed;Battery Fault”.
Errors are retrieved in a first in first out (FIFO) order. If more than 30 errors
occur, the error queue overflows and the last error in the queue is replaced
with error –350, “Queue Overflow”. Any time the queue overflows, the most
recent error is discarded.
