Status Reporting Commands
See diagram ‘‘SCPI Status System’’, on page 94 in this chapter for detailed
information of the status register structure of the power supply.
SYSTem:ERRor?
Query the power supply’s error queue. A record of up to 20 errors is stored in
the power supply’s error queue. Errors are retrieved in first-in-first-out (FIFO)
order. The first error returned is the first error that was stored. When you have
read all errors from the queue, the
ERROR annunciator turns off and the errors
are cleared. See ‘‘ Error Messages ’’, starting on page 113 for more details.
STATus:QUEStionable:CONDition?
Query the Questionable Status condition register to check CV or CC mode of
the power supply. The power supply returns a decimal value which
corresponds to the binary-weighted sum of all bits in the register. These bits
are not latched. If ‘‘0’’ is returned, the power supply is in output off or
unregulated state. If ‘‘1’’ is returned, the power supply is in the CC operating
mode and if ‘‘2’’ is returned, the power supply is in the CV operating mode. If
‘‘3’’ is returned, the power supply is in failure.
STATus:QUEStionable?
Query the Questionable Status event register. The power supply returns a
decimal value which corresponds to the binary-weighted sum of all bits in the
register. These bits are latched. Reading the event register clears it.
STATus:QUEStionable:ENABle <enable value>
Enable bits in the Questionable Status enable register. The selected bits are
then reported to the Status Byte.
STATus:QUEStionable:ENABle?
Query the Questionable Status enable register. The power supply returns a
binary-weighted decimal representing the bits set in the enable register.
*CLS
Clear all event registers and Status Byte register.
*ESE <enable value>
Enable bits in the Standard Event enable register. The selected bits are then
reported to the Status Byte.
