Questionable Event Register
You can program the bits in the Questionable Event Register to be cleared or set when an event
occurs.
When an enabled Questionable Event Register bit is set (because the enabled event occurs), the
corresponding bit B0 (MSB) and Bit B3 (QSB) of the Status Byte Register is set. The corresponding
Questionable Event Register Condition Register reflects the present status of the instrument, so it is
set while the event occurs.
When reading a register, a numeric value is returned. The binary equivalent of this value indicates
which bits in the register are set. For details, see Understanding bit settings (on page B-15
).
You can use the following commands to read and set bits in the Questionable Event Register.

The instrument returns a decimal value that corresponds to the binary-weighted sum of all bits set in
the register. See Event numbers (on page B-9
) for information about event numbers. You can use a
copy of the following table to record settings for your instrument.
