Status Reporting
Questionable Data/Signal Register Group
The Questionable Data/Signal Register Group contains information about the
quality of the Test Set’s output and measurement data. This status group is
accessed using the STATus commands. The Questionable Data/Signal Register
Group uses 16-bit registers and includes a Condition Register, Transition Filters,
an Event Register, an Enable Register, and a Summary Message. Refer to the
"Status Reporting Structure Overview" on page 260 for a discussion of status
register operation. Figure 12 shows the structure and STATus commands for the
Questionable Data/Signal Register Group.
