Status Groups
Data Questionable Status Group
NOTE Some of the bits in this status group do not apply to the E4428C, E8257D, E8267D, E8663B,
and the N5181A/82A/83A, and returns zero when queried. Other bits have changed state
content. See Table 4-7 on page 166 for more information.
The Data Questionable Status Group is used to determine the specific event that set bit 3 in the
Status Byte Register. This group consists of the Data Questionable Condition Register, the Data
Questionable Transition Filters (negative and positive), the Data Questionable Event Register, and the
Data Questionable Event Enable Register.
This is the named
status register for
the E4438C.
However, not all
signal generator
models use all of
the shown events
(i.e. some use only
a subset of the
E4438C’s status
registers).
