Status Reporting System This appendix describes the status reporting system of the Keysight E4981A.
Page 356: General Status Register Model
By generating an SRQ, you can notify the controller that the E4981A is requesting service. In other words, you can program interruption by using an SRQ. For more information on using SRQ, see “Waiting For Completion Of Measurement (detecting completion of measurement)”...
Page 357: Event Register
The event register reflects the corresponding condition of the E4981A (e.g., occurrence of an event) as a bit status. These bits continuously monitor changes in the E4981A’s state and change the bit status when the condition (e.g., change bit status to “1” if a specific event occurs) for each bit is met.
Page 358: Condition Register And Transition Filter
The E4981A's condition register and transition filter work only with the operation status register. However, the E4981A's transition filter’s setting is fixed so that bits 5, 8, 9, 10 of the event register are set to “1” when the condition register makes a positive transition (i.e., changes from 0 to 1) and bits 1, 2, 3, 4, 7, 12 of the event register are set to “1”...

Status Reporting System Status Register Structure Status Register Structure The status reporting system has the hierarchical structure shown in Figure C-3. The status byte register is a summary of registers in the lower level. This section describes the status registers in each hierarchy.

Page 362 Issuing the *CLS command will clear all bits from the operation status event register. The E4981A does not support events of the questionable status register. Therefore, all of the bits in this register are always 0. Table C-4 Status Bit Definitions of the Questionable Status Register...

Turning Off the Status Reporting System Turning Off the Status Reporting System The E4981A status reporting system can be disabled. In a disabled condition, the data in status reporting system is not updated. The benefit of disabling Status Reporting System is that it shortens the End of Measurement (EOM) time.

Page 367: Error Messages
Error Messages The Keysight E4981A provides error messages to indicate its operating status. This appendix describes the error messages of the E4981A in order of error number. To search for error messages alphabetically, refer to the Operation Manual.
Page 368: Error Messages (Order Of Error Number)
Error messages (order of error number) Error messages (order of error number) Error messages are displayed in the lower row of the E4981A’s display. You can read them out by using the SCPI command. This section provides a description of each error message and its remedy.
Page 369 -100 Command error A comprehensive syntax error has occurred for which the E4981A cannot detect further details of the error. This error code simply indicates the occurrence of a command error that is defined in IEEE488.2,11.5.1.1.4. -101 Invalid character Invalid characters have been found in the program message string.
Page 370 The length of the header exceeds 12 characters. (Refer to IEEE488.2,7.6.1.4.1.) -113 Undefined header A header not defined for the E4981A has been received. For example, “*XYZ”, which is not defined for the E4981A, is received. Header suffix out of range -114 The header suffix is out of range.
Page 371 -158 String data not allowed A string data element has been received where the E4981A does not accept any string data element. For example, a parameter must be enclosed with double quotation marks (“...”) but they are missing.
Page 372 Too much data The received block, equation, or string type program data complies with the standard, but the amount of data exceeds the limit that the E4981A can handle due to memory or device-specific conditions related to memory. Illegal parameter value -224 The parameter recieved is not correct.
Page 373 Query DEADLOCKED This indicates the status that causes a “DEADLOCKED” Query error. (Refer to IEEE488.2,6.3.1.7.) This error occurs, for example, when both input and output buffers become full and the E4981A cannot continue processing. -440 Query UNTERMINATED after indefinite response In a certain program message, a Query that requests an ambiguous response has not yet been completely executed when a different Query is received.
Page 374: Warning Messages (Warning)
Warning Messages (WARNING) Warning messages are displayed to warn users. They are displayed in the lower row of the display of the E4981A. You cannot read them out using the SCPI command.
