Page 48: Error Messages
Troubleshooting Error Messages Error Messages If an error condition occurs in the signal generator, it will always be reported to both the front panel display error queue and the SCPI (remote interface) error queue. These two queues are viewed and managed separately. The Front Panel Error Queue This queue is designed in a circular (rotating) fashion.
Page 49 Troubleshooting Error Messages -350,Queue overflow When the queue overflows, the least recent errors remain in the queue, and the most recent error is discarded. Reading an error from the head of the queue removes that error from the queue, and opens a position in the tail of the queue for a new error, if one is subsequently detected.
Page 50: Querying The Error Queue
Troubleshooting Querying the Error Queue Querying the Error Queue The queue query message is a request for the next entry from the instrument’s error queue. This queue contains an integer that can range from -32768 to 32767. Negative error numbers are reserved by the SCPI standard and are defined in this section.
Page 51: Error Numbers
Troubleshooting Error Numbers Error Numbers The system-defined error numbers are chosen on an enumerated (“1 of N”) basis. The SCPI-defined error numbers and the <error_description> portions of the error query response are listed here. The first error described in each class (for example, -100, -200, -300, -400) is a “generic”...

Page 60: Execution Error
Troubleshooting Execution Error Execution Error An error number in the range [-299 to -200] indicates that an error has been detected by the instrument’s execution control block. The occurrence of any error in this class will cause the execution error bit (bit 4) in the event status register (IEEE 488.2, section 11.5.1) to be set.
Page 61 Troubleshooting Execution Error -202 Settings lost due to rtl Indicates that a setting associated with a hard local control (see IEEE 488.2, 5.6.15) was lost when the device changed to LOCS from REMS or to LWLS from RWLS. -210 Trigger error Indicates that a or a triggering signal could not GET, *TRG,...
Page 62 Troubleshooting Execution Error -221 Settings conflict Indicates that a legal program data element was parsed but could not be executed due to the current device state (see IEEE 488.2 11.5.1.1.5). -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 defined by the device (see IEEE 488.2 11.5.1.1.5).

Page 65 Troubleshooting Execution Error -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. The definition of a math error is device-specific. -270 Macro error Indicates that a macro-related execution error occurred.
Page 66 Troubleshooting Execution Error -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, 10.7.6.4). -277 Macro redefinition not allowed Indicates that the macro label defined in the command *DMC could not be executed because the macro label was already...
Page 67 Troubleshooting Execution Error -285 Program syntax error Indicates that a syntax error appears within a downloaded program. The syntax used when parsing a downloaded program is device-specific. -286 Program runtime error Indicates that a runtime error was detected in a downloaded program.
Page 68: Device-Specific Error
The occurrence of any error in this class will cause the device-specific error bit (bit 3) in the event status register (IEEE 488.2, section 11.5.1) to be set. For positive error number descriptions see the section titled “ESG Series Signal NOTE: Generator Instrument-Specific Error Messages.”...
Page 69 Troubleshooting Device-Specific Error -312 PUD memory lost Indicates that the protected user data saved by the *PUD command has been lost. -313 Calibration memory lost Indicates that non-volatile calibration data has been lost. -314 Save/recall memory loss Indicates that the non-volatile data saved by the *SAV? command has been lost.

Page 71: Query Error
Troubleshooting Query Error Query Error An error number in the range [-499 to -400] indicates that the output queue control of the instrument has detected a problem with the message exchange protocol described in IEEE 4888.2, chapter 6. The occurrence of any error in this class will cause the query error bit (bit 2) to be set in the event status register (IEEE 488.2, section 11.5.1).
Page 72 Troubleshooting Query Error Indicates that a condition causing a DEADLOCKED query error occurred (see IEEE 488.2, 6.3.1.7). For example, both the input buffer and the output buffer are full and the device cannot continue. -440 Query UNTERMINATED after indefinite response Indicates that a query was received in the same program message after a query requesting an indefinite response was executed (see IEEE 488.2, 6.3.7.5).
