Status Register and Status Report Function
IEEE 488.2 and SCPI registers are used for status reports.
In each SCPI status register, there are the following sub registers: the CONDition register, the EVENt
register, the ENABle register, the PTRansition filter, and the NTRansition filter.
CONDition register
The CONDition register transits automatically and reflects the condition of the TOS5300 Series 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 CONDition register.
The rule for setting the bits 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 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.
