This query reports the contents of the rise register.

Using the Questionable Data Register
The Questionable Data Register conveys information about the quality of the
instrument‘s functions and outputs. The 5071A implements bits 2, 5, and 6 of the
Questionable Data Register. (Refer to the Status Reporting section of this chapter
for more details.)
The Questionable Data Register group consists of a condition register, an event
register, and an enable register as shown in Figure 5-1. The commands in the
STATus:QUEStionable subsystem control and monitor these registers.
The STATus:QUEStionable subsystem commands query the QUEStionable
Register to indicate whether an overflow has occurred for a specific function
after an associated command has executed. When any of the bits are set
(questionable data), bit 3 of the Status Register is set to 1 if enabled by the
STAT:QUES:ENAB command.
STATus:QUEStionable[:EVENt]?
This query reports contents of the QUEStionable event register, then clears the
event register.
The event register bits are determined by the settings of the corresponding rise,
fall, and condition registers.
Response format = <NR1>.
STATus:QUEStionable:CONDition?
This query reports contents of the QUEStionable condition register, non-
destructively.
Response format = <NR1>.
STATus:QUEStionable:ENABle <numeric_value>
This command sets QUEStionable enable register to the specified value.
Meaningful values are in the range 0 to 32767.
