Data Questionable Frequency Event Register
Latches transition events from the condition register as specified by the transition filters. Event
registers are destructive read- only. Reading data from an event register clears the content of that
register.

STATus:QUEStionable:FREQuency:NTRansition <value> (negative transition) or
STATus:QUEStionable:FREQuency:PTRansition <value> (positive transition) where <value> is the
sum of the decimal values of the bits you want to enable.
