STATus:QUEStionable:INSTrument[:EVENt]?
This command queries the Questionable Instrument event register. The power supply
returns a decimal value which corresponds to the binary-weighted sum of all bits in
the register and clears the register.
STATus:QUEStionable:INSTrument:ENABle <enable value>
This command sets the value of the Questionable Instrument enable register. This
register is a mask for enabling specific bits from the Questionable Instrument event
register to set the Instrument Summary bit (ISUM, bit 13) of the Questionable Status
register. The “ISUM” bit of the Questionable Status register is the logical OR of all
the Questionable Instrument event register bits that are enabled by the Questionable
Instrument enable register.
STATus:QUEStionable:INSTrument:ENABle?
This query returns the value of the Questionable Instrument enable register.
STATus:QUEStionable:INSTrument:ISUMmary<n>[:EVENt]?
This query returns the value of the Questionable Instrument Isummary event
register for a specific output of the three-output power supply. The particular output
must be specified by a numeric value. n is 1, 2, or 3. See Table 4-1 on page 74 for
the output number. 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?
This query returns 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>
This command sets the value of the Questionable Instrument Isummary enable register
for a specific output of the three-output power supply. The particular output must be
specified by a numeric value. n is 1, 2, or 3. See Table 4-1 on page 74 for the output
number. This register is a mask for enabling specific bits from the Questionable
Instrument Isummary event register to set the Instrument Summary bit (bit 1, 2, and
3) of the Questionable Instrument register. These bits 1, 2, and bit 3 are the logical
OR of all the Questionable Instrument Isummary event register bits that are enabled
by the Questionable Instrument Isummary enable register.
