D SCPI-Based Errors Error Number Description Probable Cause –100 “Command error” This is the generic syntax error for devices that cannot detect more specific errors. This code indicates only that a Command Error as defined in IEEE 488.2, 11.5.1.1.4 has occurred. –101 “Invalid character” A syntactic element contains a character which is invalid for that type; for example, a header containing an ampersand, SETUP&.
SCPI-Based Errors Error Number Description Probable Cause –110 “Command header error” An error was detected in the header. This error message should be used when the device cannot detect the more specific errors described for errors –111 through –119. –111 “Header separator error” A character which is not a legal header separator was encountered while parsing the header; for example, no white space followed the header, thus *GMC"MACRO" is an error.
SCPI-Based Errors Error Number Description Probable Cause –123 “Exponent too large” The magnitude of the exponent was larger than 32000 (see IEEE 488.2, 7.7.2.4.1). –124 “Too many digits” The mantissa of a decimal numeric data element contained more than 255 digits, excluding leading zeros (see IEEE 488.2, 7.7.2.4.1). –128 “Numeric data not allowed” A legal numeric data element was received, but the device does not accept one in this position for the header.
SCPI-Based Errors Error Number Description Probable Cause –150 “String data error” This error, as well as errors –151 through –159, are generated when parsing a string data element. This particular error message should be used if the device cannot detect a more specific error. –151 “Invalid string data” A string data element was expected, but was invalid for some reason (see IEEE 488.2, 7.7.5.2); for example, an END message was received before the terminal quote character.
SCPI-Based Errors Error Number Description Probable Cause –180 “Macro error” –181 “Invalid outside macro Indicates that a macro parameter placeholder definition” ($
SCPI-Based Errors Error Number Description Probable Cause –210 “Trigger error” ----- –211 “Trigger ignored” Indicates that a GET, *TRG, or triggering signal was received and recognized by the device but was ignored because of device timing considerations; for example, the device was not ready to respond. Note: a DT0 device always ignores GET and treats *TRG as a Command Error. –212 “Arm ignored” Indicates that an arming signal was received and recognized by the device but was ignored.
SCPI-Based Errors Error Number Description Probable Cause –222 “Data out of range” Indicates that a legal program data element was parsed but could not be executed because the interpreted value was outside the legal range as defined by the device (see IEEE 488.2, 11.5.1.1.5.) –223 “Too much data” Indicates that a legal program data element of block, expression, or string type was received and contained more data than the device could handle due to memory or related device-specific requirements.
SCPI-Based Errors Error Number Description Probable Cause –233 “Invalid version” Indicates that a legal program data element was parsed but could not be executed because the version of the data is incorrect to the device. This particular error should be used when file or block data formats are recognized by the instrument but cannot be executed for reasons of version incompatibility. For example, file or instrument version that are not supported.
SCPI-Based Errors Error Number Description Probable Cause –253 “Corrupt media” Indicates that a legal program command or query could not be executed because of corrupt media; for example, bad disk or wrong format. The definition of what constitutes corrupt media is device-specific. –254 “Media full” Indicates that a legal program command or query could not be executed because the media was full; for example, there is no room on the disk.
SCPI-Based Errors Error Number Description Probable Cause –260 “Expression error” Indicates that an expression program data element related error occurred. This error message should be used when the device cannot detect the more specific errors described for errors –261 through –269. –261 “Math error in expression” Indicates that a syntactically legal expression program data element could not be executed due to a math error; for example, a divide-by-zero was attempted.
SCPI-Based Errors Error Number Description Probable Cause –275 “Macro definition too long” Indicates that a syntactically legal macro program data sequence could not be executed because the string or block contents was too long for the device to handle (see IEEE 488.2, 10.7.6.1). –276 “Macro recursion error” Indicates that a syntactically legal macro program data sequence could not be executed because the device found it to be recursive (see IEEE 488.2, 10.7.6.6).
SCPI-Based Errors Error Number Description Probable Cause –284 “Program currently running” –285 “Program syntax error” Indicates that a syntax error appears in a downloaded program. The syntax used when parsing the downloaded program is device-specific. –286 “Program runtime error” ----- –290 “Memory use error” Indicates that a user request has directly or indirectly caused an error related to memory or , this is not the same as “bad” memory.
SCPI-Based Errors Error Number Description Probable Cause –312 “PUD memory lost” Indicates that the protected user data saved by the *PUD command has been lost. –313 “Calibration memory lost” Indicates that nonvolatile calibration data used by the *CAL? command has been lost. –314 “Save/Recall memory lost” Indicates that the nonvolatile data saved by the *SAV? command has been lost.
SCPI-Based Errors Error Number Description Probable Cause –363 “Input buffer overrun” Software or hardware input buffer on serial port overflows with data caused by improper or nonexistent pacing. –365 “Time out error” This is a generic device-dependent error. –400 “Query error” This is the generic query error for devices that cannot detect more specific errors. This code indicates only that a Query Error as defined in IEEE 488.2, 11.5.1.1.7 and 6.3 has occurred.
SCPI-Based Errors Error Number Description Probable Cause –700 “Request control” The instrument requested to become the active IEEE 488.1 controller-in-charge. –800 “Operation complete” The instrument has completed all selected pending operations in accordance with the IEEE 488.2, 12.5.2 synchronization protocol.
