SCPI Status Registers
Three type of status registers are available: Condition, Event, and Enable.
Condition registers always show the current status of the instrument. Bits may turn on
and back off between reads. The status read is the status of instrument at the moment of
the read. Condition registers include:
*STB?
Status Byte Register
*ESR? Standard Event Status Register
STAT:OPER:COND? Operation Status Condition Register
STAT:QUES:COND? Questionable status Condition Register
Event registers do not show the current state but flag the bits in the condition registers
that have changed since the last time the event register was read. When an event register
is read it is reset to zero.
STAT:OPER:EVENT?
Operation Status Event Register
STAT:QUES:EVENT? Questionable Status Event Register
Enable registers are set by the user to create summary bits. If the user sets a bit in the
enable register, when the instrument sets the corresponding bit in the event register a
summary bit in the Status Byte Register is set.
