Agilent CSA STATus Register Model
Questionable Frequency Event Query
This query returns the decimal value of the sum of the bits in the Questionable Frequency
Event register.
NOTE
The register requires that the associated PTR or NTR filters be set
before a condition register bit can set a bit in the event register. The
data in this register is latched until it is queried. Once queried, the
register is cleared.

Questionable Frequency Negative Transition
This command determines which bits in the Questionable Frequency Condition register
will set the corresponding bit in the Questionable Frequency Event register when the
condition register bit has a negative transition (1 to 0). The variable <integer> is the sum
of the decimal values of the bits that you want to enable.
