Error Messages
Error Messages
System and device-specific errors are managed by the FVA-3150 Variable
Attenuator. The generic format for error messages is illustrated in the
following figure.
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?,
ERR?, or LERR? command to read the most recent message. The error
message buffer is initialized when starting the Variable Attenuator, when
executing the *CLS command, or by reading the last message stored in the
buffer.
