General Programming 8
M8190A User’s Guide 191
8.7.3.5 :STATus:QUEStionable:PTRansition[?]
Set or queries the positive-transition register in the questionable status group. A
positive transition filter allows an event to be reported when a condition changes
from false to true. Setting both positive/negative filters true allows an event to be
reported anytime the condition changes. Clearing both filters disable event reporting.
The contents of transition filters are unchanged by *CLS and *RST.
8.7.4 Operation Status Subsystem
The Operation Status register contains conditions which are part of the instrument’s
normal operation.

The following commands access the operation status group.
8.7.4.1 :STATus:OPERation[:EVENt]?
Reads the event register in the operation status group. It’s a read-only register. Once
a bit is set, it remains set until cleared by this command or *CLS command. A query
of the register returns a decimal value which corresponds to the binary-weighted
sum of all bits set in the register.
