Trigger Frequency Readout
The oscilloscope counts the rate a t which trigger events occur to
determine trigger frequency and displays the frequency in the lower
right corner of the screen.
Key Points
Trigger When. The pulse width of the source must be ≥ 5 ns for the
oscilloscope to detect the pulse.
