5.6 Error Display

The waveform generator can store up to 20 syntax or hardware errors in

its error queue. Each error string may contain up to 255 characters. The

waveform generator beeps every time it detects an error (unless the

beeper is turned off). Errors are stored in first-in-first-out (FIFO) order

and they are cleared once read. To clear the error queue from the remote

interface, use the

*CLS command. The error queue will not be cleared by

the *RST command, but will be cleared when the waveform generator is

turned off. Refer to Chapter 7 for more details about the error queue and

error messages.
