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.
