Status Reporting Commands
Refer to Figure 3- 1 on page 104 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 the 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. Refer to Chapter 4,
“Error Messages” for more details.
STATus:QUEStionable:CONDition?
Query the Questionable Status condition register to check
the 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 the
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 has a failure.
STATus:QUEStionable[:EVENt]?
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.
