Status Groups
Data Questionable Modulation Status Group
NOTE This status group does not apply to the N5161A/81A and the N5162A/82A, and returns zero
when queried. See Table 4- 11 on page 196 for more information.
The Data Questionable Modulation Status Group is used to determine the specific event that set bit 7
in the Data Questionable Condition Register. This group consists of the Data Questionable Modulation
Condition Register, the Data Questionable Modulation Transition Filters (negative and positive), the
Data Questionable Modulation Event Register, and the Data Questionable Modulation 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).
