Status Groups
Data Questionable Frequency Status Group
NOTE Some bits in this status group do not apply to the N5161A/62A/81A/82A/83A, E4428C,
E8257D, E8663B, and the E8663D and returns zero when queried. See Table 4- 10 on
page 193 for more information.
The Data Questionable Frequency Status Group is used to determine the specific event that set bit 5
in the Data Questionable Condition Register. This group consists of the Data Questionable Frequency
Condition Register, the Data Questionable Frequency Transition Filters (negative and positive), the
Data Questionable Frequency Event Register, and the Data Questionable Frequency 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).
