The Questionable Data Register
The Questionable Data register group provides information about the
quality of the instrument’s measurement results. Any or all of these
conditions can be reported to the Questionable Data summary bit through
the enable register. To set the enable register mask, you must write a
decimal value to the register using the STATus:QUES:ENABle command.
A measurement overload condition is always reported in both the
Questionable Data event register (bits 0, 1, 2, 9, or 10) and the Standard
event register (bit 3). However, no error message is recorded in the
instrument’s error queue.
