Programming the Status Register System
Status Groups
Status Groups
The Standard Operation Status Group and the Data Questionable Status Group
consist of the registers listed below. The Standard Event Status Group is similar
but does
not
have negative or positive transition filters or a condition register.
Condition
Register
A condition register continuously monitors the
hardware and firmware status of the signal generator.
There is no latching or buffering for a condition register;
it is updated in real time.
Negative
Transition
Filter
A negative transition filter specifies the bits in the
condition register that will set corresponding bits in the
event register when the condition bit changes from 1 to
0.
Positive
Transition
Filter
A positive transition filter specifies the bits in the
condition register that will set corresponding bits in the
event register when the condition bit changes from 0 to
1.
Event
Register
An event register latches transition events from the
condition register as specified by the positive and
negative transition filters. Once the bits in the event
register are set, they remain set until cleared by either
querying the register contents or sending the
*CLS
command.
Event
Enable
Register
An enable register specifies the bits in the event register
that generate the summary bit. The signal generator
logically ANDs corresponding bits in the event and
enable registers and ORs all the resulting bits to
produce a summary bit. Summary bits are, in turn, used
by the Status Byte Register.
A status group is a set of related registers whose contents are programmed to
produce status summary bits. In each status group, corresponding bits in the
condition register are filtered by the negative and positive transition filters and
stored in the event register. The contents of the event register are logically
ANDed with the contents of the enable register and the result is logically ORed
to produce a status summary bit in the Status Byte Register.
