106 TDS1000/2000-Series Digital Oscilloscope User ManualTrigger Frequency ReadoutThe oscilloscope counts the rate at which trigger events occ ur todetermine trigger frequency a nd displays the frequency in the lowerright corner of the screen.Key Points
Trigger When. The pulse width of the source must be ≥5 ns for the
oscilloscope to detectthe pulse.
