Error Messages
Error messages are issued when an incorrect remote command is sent to
your Model 645 waveform generator for execution. This may occur for
reasons such as incorrect command syntax, giving the parameters of a
command that violate some system constraints, hardware failures and
so. All possible error messages are categorized and listed in this chapter
for your reference. If you cannot find a particular error message in this
chapter, contact your service representative.
Error messages are stored in an error queue in Model 645 and may be
retrieved in the first-in-first-out (FIFO) order. The first error returned is
the first error that was stored. Model 645 beeps once each time an error
occurs and the ERROR annunciator is lit whenever there are error
messages in the error queue. Only when all the errors in the queue are
read, the ERROR annunciator is turned off.
Should more than 20 errors have existed, the last error stored in the
queue (the most recent error) is replaced with -350, “Queue Overflow”.
No additional errors are saved until errors are read and cleared from the
queue. If there is no error in the error queue, the waveform generator
responds with +0, “No Error”.
The error queue is cleared with a power cycle or a *CLS (clear status)
command. The *RST (reset) command does not clear the error queue.
