Error Messages

GPIB Messages

Execution Errors

These are error messages in the range -200 to -299. They indicate that an execution error has been detected by the execution control block.

An execution error is signaled by the execution error bit (bit 4) in the event status register.

-200 Execution error

This indicates that an execution error has occurred but the control block cannot be more specific.

-201 Invalid while in local

This command is invalid because it conflicts with the configuration under local control.

-202 Settings lost due to rtl

A local setting was lost when the instrument was changing from remote to local control, or from local to remote control.

-220 Parameter error

This indicates that a parameter error has occurred but the control block cannot be more specific.

-221 Settings conflict

A valid parameter was received, but could not be used during execution because of a conflict with the current state of the instrument.

-222 Data out of range

The data, though valid, was outside the range allowed by the instrument.
