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.
