Status Register and Status Report Function
IEEE488.2 and SCPI registers are used for the status reports.
In each SCPI status register, there are sub registers, CONDition register, EVENt register,
ENABle register, PTRansition filter, and NTRansition filter.
The SCPI status register structure as shown in the figure below. The character "+"
represents the logic sum of the register bits.
Architecture
CONDition register
The transition of the CONDition register is automatic and reflects the condition of the
KFM2005 in real-time. Reading this register does not affect the contents.
EVENt register
The EVENt register bits are automatically set according to the changes in the CONDition
register. The rule varies depending on the positive and negative transition filters
(PTRansition and NTRansition). The EVENt register is reset when it is read.
ENABle register
The ENABle register enables the reports to the summary bit or status bit of the event bit.
Transition filter
PTRansition (positive transition) filter to report events when the condition changes from
false to true.
NTRansition (negative transition) filter to report events when the condition changes from
true to false.
If both the positive filter and the negative filter are set to true, events can be reported each
time the status changes.
If both filters are cleared, event reporting is disabled.
