Error Messages
This chapter describes the error messages and how they are generated. The possible causes
for the generation of the error messages are also listed in
Table 1-10 on page 1-48 .
Error Queue As errors are detected, they are placed in an error queue. This queue is first in, first out. If
the error queue overflows, the last error in the queue is replaced with error –350, “Queue
overflow.” Anytime the error queue overflows, the oldest errors remain in the queue, and the
most recent error is discarded. The length of the instrument's error queue is 30 (29 positions
for the error messages, and 1 position for the “Queue overflow” message). Reading an error
from the head of the queue removes that error from the queue, and opens a position at the
tail of the queue for a new error. When all errors have been read from the queue, subsequent
error queries return 0, “No error.”
The error queue is cleared when any of the following occur:
• the instrument is powered up,
• a *CLS command is sent,
• the last item from the queue is read, or
• the instrument is switched from talk only to addressed mode on the front panel.
