Introduction
Error messages are entered in the error/event queue of the status reporting system in the
remote control mode and can be queried with the command SYSTem:ERRor?. The
answer format of instrument to the command is as follows:
<error code>, "<error description>;<remote control command concerned>"
The indication of the remote control command with prefixed semicolon is optional.
Example
The command "TEST:COMMAND" generates the following answer to the query
SYSTem:ERRor? :
-113,"Undefined header;TEST:COMMAND"
The subsequent list contains the description of error texts displayed on the instrument.
Distinction is made between error messages defined by SCPI, which are marked by
negative error codes, and the device-specific error messages for which positive error
codes are used.
The right-hand column in the following tables contains the error text in bold that is
entered in the error/event queue and can be read out by means of query SYSTem:ERRor?.
A short explanation of the error cause is given below. The left-hand column contains the
associated error code.
Events that generate command errors shall not generate execution errors, device-specific
errors, or query errors; see the other error definitions in this chapter.
Command Error
An <error/event number> in the range [ -199 , -100 ] indicates that an IEEE 488.2 syntax
error has been detected by the instrument’s parser. The occurrence of any error in this
class causes the command error bit (bit 5) in the event status register (IEEE 488.2, section
11.5.1) to be set. One of the following events has occurred:
•
An IEEE 488.2 syntax error has been detected by the parser. That is, a controller-
to-device message was received that is in violation of the IEEE 488.2 standard.
Possible violations include a data element that violates the device listening
formats or whose type is unacceptable to the device.
•
An unrecognized header was received. Unrecognized headers include incorrect
device-specific headers and incorrect or unimplemented IEEE 488.2 common
commands.
