Status and

Event

Commands

Clear Status Command

Clears all Event Registers, including the Status Byte, the Standard Event Status and the Error Queue.

*CLS

or the multichannel equivalent:

STATus<channel>:CLEar

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.

The Power-on Status Clear command determines if the Standard Event Status Enable Register is cleared at power-on.

E.g.

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?

or the multichannel equivalent: STATus<channel>:STANdard:ENABle <status-enable> STATus<channel>:STANdard:ENABle?

Standard Event Status Register

The Standard Event Status Register query allows the user to determine the current contents of the Standard Event Status Register. (See “Standard Event Status Register” on page 77.) Reading this register clears it.

Command: *ESR?

SCPI equivalent for multichannel use:

STATus<channel>:STANdard[:EVENt]?

Service Request Enable Register

The Service Request Enable Register allows the user to select the reasons for the power supply to issue a service request. The Service Request Enable Register allows the user to select which summary messages in the Status Byte Register may cause service requests.
