Questionable Calibration Register

Language Reference

STATus Subsystem

Key Type:	There is no equivalent front panel key.
Factory Preset
and *RST:	32767 (all 1’s)
Range:	0 to 32767

Questionable Calibration Condition :STATus:QUEStionable:CALibration:CONDition?

This query returns the decimal value of the sum of the bits in the

Questionable Calibration Condition register.

NOTE	The data in this register is continuously updated and reflects the
	current conditions.
	Key Type:	There is no equivalent front panel key.

Questionable Calibration Enable

:STATus:QUEStionable:CALibration:ENABle <number>

:STATus:QUEStionable:CALibration:ENABle?

This command determines what bits in the Questionable Calibration Condition Register will set bits in the Questionable Calibration Event register, which also sets the Calibration Summary bit (bit 8) in the Questionable Register. The variable <number> is the sum of the decimal values of the bits you want to enable.

Key Type:	There is no equivalent front panel key.
Example	STAT:QUES:CAL:ENABLE 16384 could be used if you
	have turned off the automatic alignment and you want
	to query if an alignment is needed.
Factory Preset
and *RST:	32767 (all 1’s)
Range:	0 to 32767

Questionable Calibration Event Query

:STATus:QUEStionable:CALibration[:EVENt]?

This query returns the decimal value of the sum of the bits in the

Questionable Calibration Event register.
