Interrogating the Instrument Status
Standard Event Status Register Group
Standard Event Status Register Group
The Standard Event Status register group is a 16-bit register group which gives general
purpose information about the instrument. It is unique in that it is the only reporting
register group programmed using SCPI common commands while the other reporting
registers are programmed using the SCPI Status command set.
NOTE This register conforms, in part, to the generalized status register model.
It comprises of an Event and Enable register, but no Condition register
or Transition Filter. Therefore all positive (true) states occurring in this
register are latched.
