Status Reporting Commands
4
See the table on page 257 for the register bit definitions.
*ESR?
Query the Standard Event Status Register
. Once a bit is set, it remains
set until cleared by a *CLS (clear status) command or queried by this
command. A query of this register returns a decimal value which
corresponds to the binary-weighted sum of all bits set in the register.
*ESE <enable value>
*ESE?
Enable bits in the Standard Event Status Register to be reported in the
Status Byte. The selected bits are summarized in the “Standard Event” bit
(bit 5) of the Status Byte Register. The *ESE? query returns a decimal
value which corresponds to the binary-weighted sum of all bits enabled
by the *ESE command.
•A *CLS (clear status) does not clear the enable register but it does
clear all bits in the event register.
•A STATus:PRESet does not clear the bits in the Status Byte
enable register.
•A *PSC 0 preserves the contents of the enable register through
power cycles.
