Error Messages Format

Error Messages Format

System and device specific errors are managed by the FLS-5834A CD/PMD
Analyzer Source. The generic format for error messages is illustrated in the
following figure.

As shown in the above figure, the message contains three parts:

³

Error number

³

Error description

³

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? command to read the most recent message. The error message
buffer is initialized when starting the CD/PMD Analyzer Source, when
executing the *CLS command, or by reading the last message stored in the
buffer.

Note: Error messages ending in a negative number are SCPI-based errors.
