Command Reference 8-109

:STATus: OPERation?

Read Operation Status, Event

Reads out the contents of the operation event status register. Reading the Opera

tion Event Register clears the register. See figure on page 8-107.

Returned Format: <Decimal data>¿

<dec.data> = the sum (between 0 and 368) of all bits that are true. See table on page 8-108.

Complies with standards: SCPI 1991.0, confirmed.

:STATus :PRESet

Enable Device Status Reporting

This command has an SCPI standardized effect on the status data structures. The

purpose is to precondition these toward reporting only device-dependent status

data.

–

It only affects enable registers. It does not change event and condition registers.

–

The IEEE-488.2 enable registers, which are handled with the common commands *SRE and

*ESE remain unchanged.

–

The command sets or clears all other enable registers. Those relevant for this counter are as

follows:

–

It sets all bits of the Device status Enable Registers to 1.

–

It sets all bits of the Questionable Data Status Enable Registers and the Operation Status En

able Registers to 0.

–

The following registers never change in the counter, but they do conform to the standard

:STATus:PRESet values.

–

All bits in the positive transition filters of Questionable Data and Operation status registers

are 1.

–

All bits in the negative transition filters of Questionable Data and Operation status registers

are 0.
