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 121 for a discussion of status
register operation. Figure 6-10 on page 147 shows the structure and
