STATus:QUEStionable:INSTrument:ISUMmary<n>[:EVENt]?
Return the value of the Questionable Instrument Isummary Event register for a
specific output of the two-output power supply. The particular output must be
specified by a numeric value. n is 1 or 2. ‘‘1’’ selects output1, and ‘‘2’’ selects output2.
The event register is a read-only register which holds (latches) all events. Reading the
Questionable Instrument Isummary Event register clears it.
STATus:QUEStionable:INSTrument:ISUMmary<n>:CONDition?
Return the CV or CC condition of the specified instrument. If “2” is returned, the
queried instrument is in the CV operating mode. If “1” is returned, the queried
instrument is in the CC operating mode. If “0” is returned, the outputs of the
instrument are off or unregulated. If ‘3” is returned, the instrument is in the hardware
failure. n is 1, 2, or 3.
STATus:QUEStionable:INSTrument:ISUMmary<n>:ENABle <enable
value>
Set the value of the Questionable Instrument Isummary Enable register for a specific
output of the two-output power supply. The particular output must be specified by a
numeric value. n is 1 or 2. ‘‘1’’ selects output1, and ‘‘2’’ selects output2. This register
is a mask for enabling specific bits from the Questionable Instrument Isummary Event
register to set the Instrument Summary bit (bit 1 and 2) of the Questionable Instrument
register. These bits 1 and 2 are the logical OR of all the Questionable Instrument
Isummary Event register bits that are enabled by the Questionable Instrument
Isummary Enable register.
STATus:QUEStionable:INSTrument:ISUMmary<n>:ENABle?
This query returns the value of the Questionable Instrument Isummary Enable register.
n is 1 or 2.
*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.
*ESE?
Query the Standard Event Enable register. The power supply returns a decimal value
which corresponds to the binary-weighted sum of all bits in the register.
