MEASURING PHASE USING THE CURSORS
In this example you will use the cursors to measure the
phase difference between the waveforms on INPUT A and
B. Use the two waveforms from the dual input three-phase
measurement in the previous exercise. Cursors allow you
to make accurate digital measurements. It is advised that
you first press to freeze the waveforms to be
measured.
Measure the two sine wave waveforms as explained
in the previous example.
Return to the main menu.
Set the test tool to Scope mode.
