Instrument Status
STATus:FAILure:EVENt
The bits in this register indicate that a major hardware element of the instrument has
failed. No capability is provided to query the condition register, setup the enable register,
nor setup the positive or negative transition filters. This is because failures within this
category are non-recoverable, and as such the enable registers are pre-defined.
Refer to table 3-4 on page 3-11 for a detailed definition of the bits within the failure status
register group.
STATus:PRESet
The PRESet command is an event that configures the SCPI and device dependent status
data structures, such that the device dependent events are reported at a higher level
through the mandatory part of the status reporting structures.
The PRESet command affects only the enable register and the transition filter registers
for the SCPI mandated and device dependent status data structures. PRESet does not
affect either the “status byte” or the “standard event status” as defined by IEEE 488.2.
PRESet does not clear any of the event registers. The *CLS command is used to clear all
event registers in the device status reporting mechanism.
For the device dependent status data structures, the PRESet command sets the enable
register to all one's and the transition filter to recognize both positive and negative
transitions. For the SCPI mandatory status data structures, the PRESet command sets the
transition filter registers to recognize only positive transitions and sets the enable register
to zero.
