Standard Event Status Register (SESR)
The standard event status register sets bits for specific events during power supply operation.
All bits in the standard event status registers are set through the error event queue. The
register is defined by IEEE 488.2 register and is controlled using 488.2 common commands:
*ESE, *ESE?, and *ESR? as well as SCPI aliases for multichannel use.
Standard Event Status Enable Register
The Event Summary Enable command determines which bits in the Standard Event Status
Register are summarized in the Event Summary Bit (ESB) of the Status Byte. This register
will be cleared at power up. To enable events, you must make the logical sum of all values for
the events that you to be reported and send this parameter in decimal format.
See the table that follows for values for the events to be enabled in <status-enable>
parameter.
For example, sending *ESE 16 sets bit 4 of the Standard Event Status Enable Register. This
will cause the Event Summary bit (ESB) in the Status Byte to be set whenever the Execution
Error bit (bit 4) in the Standard Event Status Register gets set.
Command:
*ESE <status-enable>, *ESE?
The SCPI equivalent for multichannel use:
[:]STATus[<channel(s)>]:STANdard:ENABle <status-enable>
[:]STATus[<channel(s)>]:STANdard:ENABle?
Standard Event Status Register Query
The Standard Event Status Register query allows you to determine the current contents of the
Standard Event Status Register. (See “Standard Event Status Register (SESR)” on page 131.
Reading this register clears it.
Command:
*ESR?
The SCPI equivalent for multichannel use:
[:]STATus[<channel(s)>]:STANdard[:EVENt]?
