A-2
BIT 4886 120413
A.4 *ESE? — STANDARD EVENT STATUS ENABLE QUERY
*ESE?
Syntax: *ESE? Return value: Integer> value per Table A-2.
Description: Returns the mask stored in the Standard Event Status Enable Register. Contents of Standard
Event Status Enable register (*ESE) determine which bits of Standard Event Status register (*ESR)
are enabled, allowing them to be summarized in the Status Byte register (*STB). All of the enabled
events of the Standard Event Status Enable Register are logically ORed to cause ESB (bit 5) of the
Status Byte Register to be set (1 = set = enable function, 0 = reset = disable function). (See example,
Figure A-1.)
A.5 *ESR? — EVENT STATUS REGISTER QUERY
*ESR?
Syntax: *ESR?
Return value: (Value = contents of Event Status register as defined in Table A-2.)
Description: Causes the power supply to return the contents of the Standard Event Status register. After it
has been read, the register is cleared. The Standard Event Status register bit configuration is
defined in Table A-2 (1 = set, 0 = reset). The error bits listed in Table A-2 are also related to error
codes produced during parsing of messages and to errors in the power supply (see PAR. B.80)
• Any 1xx type error sets the Command error bit (5) see.
• Any 2xx type error sets the Execution error bit (4).
• Any 3xx type error sets the Device error bit (3). The Device error bit will be set when Current Error
or Voltage Error is detected and the corresponding Status Questionable bit is set (see PAR. B.28).
• Any 4xx type error sets the Query error bit (2).
Related Commands: *CLS, *ESE, *OPC. (See example, Figure A-1.)
A.6 *IDN? — IDENTIFICATION QUERY
*IDN?
Syntax: *IDN?
Return value: Character string
Description: Identifies the instrument. This query requests identification. The power supply returns a string
which contains the manufacturer name, the model, the serial number and the firmware level. The
character string contains the following fields: , , , ,
