4288A’s fixed point display is the same as that of the 4278A. The display (LCD) of the 4288A is smaller than that of the 4278A. This prevents the 4288A from simultaneously displaying all of the items that can be displayed at one time with the 4278A, as shown in Table B-12.

Status Reporting System This appendix describes the status reporting system of the Agilent 4288A.
Page 250: General Status Register Model
By generating an SRQ, you can notify the controller that the 4288A 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 251: Event Register
The event register reflects the corresponding condition of the 4288A (e.g., occurrence of an event) as a bit status. These bits continuously monitor changes in the 4288A’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 252: Condition Register And Transition Filter
The 4288A's condition register and transition filter work only with the operation status register. However, the 4288A'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. Each bit of the status register is described in Table C-1 through Table C-3.
Page 254 Status Reporting System Status Register Structure Table C-1 Status Bit Definitions of Status Byte (STB) Name Description Position 0 to 2 Not used Always 0 Questionable Status Register Set to “1” when one of the enabled bits in the status event Summary status register is set to “1.”...
Page 255 Set to “1” when the 4288A receives a data output request but there is no data to output. Set to “1” when the data of the 4288A's output queue has been cleared because of a new message received before the completion of data output.
Page 256 “Trigger system” on page 52. Issuing the *CLS command will clear all bits from the operation status event register. The 4288A does not support events of the questionable status register. Therefore, all of the bits in this register are always 0.

Error Messages The Agilent 4288A provides error messages to indicate its operating status. This appendix describes the error messages of the 4288A in order of error number. To search for error messages alphabetically, refer to the Operation Manual.
Page 266: Error Messages (Order Of Error Number)
RAM test failed The RAM test at power-on has failed. If this error occurs, the 4288A makes a beep sound and stops. The hardware is at fault and needs repair. Contact an Agilent Technologies sales office or the VAR from which you purchased the instrument.
Page 267 A1 board test failed The A1 board test at power-on has failed. If this error occurs, the 4288A makes a beep sound and stops. The hardware is at fault and needs repair. Contact an Agilent Technologies sales office or the VAR from which you purchased the instrument.
