STATus:QUEStionable Subsection
This subsection controls the SCPI-defined status-reporting structures.
Questionable Calibration Condition
STATus :QUEStionable :CALibration :CONDition ?
This query returns the decimal value of the sum of the bits in th e
Questionable Calibration Condition register .
NOTE
The data in this register is continuously updated and reflects the
current conditions.
Questionable Calibration Enabl e
STATus :QUEStionable :CALibration :ENABle <number >
STATus :QUEStionable :CALibration :ENABle ?
This command determines which bits in the Questionable Calibratio n
Condition Register will set bits in the Questionable Calibration Even t
register, which also sets the Calibration Summary bit (bit 8) in th e
Questionable Register. The variable <number> is the sum of th e
decimal values of the bits you want to enable .
Factory Preset
and *RST : 32767 (all 1's )
Range : 0 to 3276 7
Questionable Calibration Event Query
STATus :QUEStionable :CALibration[ :EVENt] ?
This query returns the decimal value of the sum of the bits in th e
Questionable Calibration Event register.
NOTE
The register requires that the equivalent PTR or NTR filters be set
before a condition register bit can set a bit in the event register.
The data in this register is latched until it is queried . Once queried, the
data is cleared.
