Frequency

Frequency is defined as 1/Period. Period is defined as the time between
the middle threshold crossings of two consecutive, like- polarity edges. A
middle threshold crossing must also travel through the lower and upper
threshold levels which eliminates runt pulses. The X cursors show what
portion of the waveform is being measured. The Y cursor shows the
middle threshold point.

To isolate an event for frequency measurement
The following figure shows how to use Zoom mode to isolate an event for
a frequency measurement.
You may need to change the measurement window setting so that the
measurement is made in the lower, Zoom window. See
Window with Zoom Display"
If the waveform is clipped, it may not be possible to make the
measurement.
