STATus:QUEStionable:VOLTage:ENABle < mask >
STATus:QUEStionable:VOLTage:ENABle?
The STATus:QUEStionable:VOLTage:ENABle command sets the value of the
enable register for the VOLTage status group.
The STATus:QUEStionable:VOLTage:ENABle query returns an integer representing
the value of the enable register for the VOLTage status group.
The enable register specifies which bits in the event register can generate a summary
bit. The instrument logically ANDs corresponding bits in the event and enable
registers, and ORs all the resulting bits to obtain a summary bit. Summary bits are,
in turn, recorded in another register. The questionable voltage status summary bit is
recorded in the Questionable Condition Register. Enable registers are read-write.
Enable registers are not affected by *CLS (Clear status). Querying enable registers
does not affect them.
Parameters
Returned Data
Comments
•
Refer to STATus:QUEStionable:VOLTage:CONDition? for a description of
each bit in the VOLTage status group.
•
If *PSC was set to 0 prior to power-down, then at power-on, the enable
registers are loaded from non-volatile memory. Therefore, any values that you
have stored (
SYSTem:NVSave command) are returned to the registers.
However, if *PSC was set to 1, then at power-on the factory defaults are
returned. The value 487 includes all power supples except P5STby and P5EXt.
Error Conditions
The following table lists the most common error conditions and causes. Error
numbers and corresponding messages can be found using
SYSTem:ERRor?
query.
Reset Condition
*RST resets register the last value saved by the SYST:NVS command. Use
STATus:PRESet to clear the enable registers of the OPERation status group and the
QUEStionable status group.
