Trigger Frequency Readout
The oscilloscope counts the rate at which triggerable events occur to determine
trigger frequency and displays the frequency in the lower right corner of the
screen.
NOTE.
The trigger frequency readout shows the frequency of events the
oscilloscope might consider to be a trigger, and may be less than the frequency of
the input signal in Pulse Width trigger mode.
