Failure Status Register Group
Failure Status Register Group
The Failure Status register is a 16-bit event register, however in the Agilent 71612 Series
only 10 bits are used. The bits in this register are set to indicate a major hardware element
of the instrument has failed.
NOTE There is no Condition or Enable registers for the Failure Status register.
Any failures in the instrument are latched and indicated by this register.
The FAIL bit (bit 0) in the Status Byte register is automatically set
whenever any bit in the Failure Status register is set. Failures of this
type are not recoverable.
