Preset the Status Byte
:STATus:PRESet
Sets bits in most of the enable and transition registers to their default
state. It presets all the Transition Filters, Enable Registers, and the
Error/Event Queue Enable. It has no effect on Event Registers,
Error/Event QUEue, IEEE 488.2 ESE, and SRE Registers as described
in IEEE Standard 488.2-1992, IEEE Standard Codes, Formats,
Protocols and Common Commands for Use with ANSI/IEEE Std
488.1-1987.NewYork,NY,1992.
Key Type: There is no equivalent front panel key.
Questionable Register
Questionable Condition
:STATus:QUEStionable:CONDition?
This query returns the decimal value of the sum of the bits in the
Questionable Condition register.
NOTE The data in this register is continuously updated and reflects the
current conditions.
Key Type: There is no equivalent front panel key.
Questionable Enable
:STATus:QUEStionable:ENABle <number>
:STATus:QUEStionable:ENABle?
This command determines which bits in the Questionable Event
register will set the Questionable Status Summary bit (bit3) in the
Status Byte Register. The variable <number> is the sum of the decimal
values of the bits you want to enable.
NOTE The preset condition is all bits in this enable register set to 0. To have
any Questionable Events reported to the Status Byte Register, one or
more bits need to be set to 1. The Status Byte Event Register should be
queried after each measurement to check the Questionable Status
Summary (bit 3). If it is equal to 1, a condition during the test may have
made the test results invalid. If it is equal to 0, this indicates that no
hardware problem or measurement problem was detected by the
analyzer.
