Architecture
IEEE 488.2 and SCPI registers are used for status reports.
In each SCPI status register, there are the following sub registers: the CONDition reg-
ister, the EVENt register, the ENABle register, the PTRansition filter, and the NTRan-
sition filter.
CONDition register
Transitions of the CONDition register are automatic and reflect the condition of the
product in real time. Reading this register does not affect its contents.
EVENt register
The EVENt register bits are automatically set according to the changes in the CON-
Dition register. The rule for setting the bits varies depending on the positive and neg-
ative transition registers (PTRansition and NTRansition). The EVENt register is reset
when it is read.
ENABle register
The ENABle register enables reports to the summary bit or status bit of the event bits.
Transition filters
Use the PTRansition (positive transition) filter to report events when the condition
changes from false to true.
Use the NTRansition (negative transition) filter to report events when the condition
changes from true to false.
If both the positive filter and negative filter are set to true, events can be reported
each time the status changes.
If both filters are cleared, event reporting is disabled.
