STATus:QUEStionable:CURRent:ENABle?
The STATus:QUEStionable:CURRent:ENABle command sets the value of the
enable register for the CURRent status group.
The STATus:QUEStionable:CURRent:ENABle? query returns an integer
representing the value of the enable register for the CURRent 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 Current 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:CURRent:CONDition? for a description of
each bit in the CURRent 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.
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.
