Error Messages
Error Messages
The Optical Power Meter can manage both system and device-specific
errors. The generic format for error messages is illustrated below.
As shown in the above figure, the message contains three parts: the error
number, error description, and device dependent information. All error
messages are stacked in a FIFO buffer. When there is at least one message
in the buffer, bit 2 of the Status Byte Register is set to 1. Use the SYST:ERR?
query to read the most recent message. The error message buffer is
initialized when starting the Optical Power Meter, when executing the *CLS
command, or by reading the last message stored in the buffer.
