STATus Subsystem
Questionable Frequency Enable
This command determines which bits in the Questionable Frequency Condition Register will set bits in the
Questionable Frequency Event register, which also sets the Frequency Summary bit (bit 5) in the
Questionable Register. The variable <integer> is the sum of the decimal values of the bits you want to
enable.
Mode All
Remote Command
:STATus:QUEStionable:FREQuency:ENABle <integer>
:STATus:QUEStionable:FREQuency:ENABle?
Example STAT:QUES:FREQ:ENAB 2 Frequency Reference Unlocked will be reported to the Frequency
Summary of the Status Questionable register.

Questionable Frequency Event Query
This query returns the decimal value of the sum of the bits in the Questionable Frequency Event register.
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.
