This appendix describes the error messages of the 4287A in alphabetical order. To search error messages in order of error number, refer to the 4287A Programming Manual.
Error Messages A21 board can't be detected. The instrument will be automatically shutdown in 20 seconds. Error messages are displayed at the top of the 4287A's LCD. Error messages generated during the execution of GPIB commands are preceded by the string “[GPIB]” or “[TELNET]” and can be read out using the GPIB command. This section gives you the description of each error message and its remedy. NOTE Errors with a negative error number are basically general errors for GPIB instruments defined by IEEE488.2.
6 Additional standards needed Before the completion of all of the data measurement required for calculating the calibration/compensation coefficients, a GPIB command requiring any of the measurement data was sent. For example, when only the OPEN and SHORT measurements of the calibration kit have been complete, the :CORR1:COLL:SAVE command, which performs calculation of the calibration coefficients, was sent. 1. Chapter Title Error Messages Additional standards needed Measure all the required data. 2.
Error Messages Data corrupt or stale D -230 Data corrupt or stale The data may be invalid or a newly initiated read operation has not been completed since the latest access. -222 Data out of range A data element (that did not violate the standard) out of the defined range of the 4287A was received. -104 Data type error The parser recognized impossible data elements. For example, numeric value or string data was expected, but block data was sent.
