FallEdgeCnt
: The number of negative transitions from the high
reference value to the low reference value in the waveform.
Area : The area of the whole waveform within the screen and the unit is
voltage-second. The area measured above the zero reference (namely the vertical
offset) is positive; the area measured below the zero reference is negative. The
area measured is the algebraic sum of the area of the whole waveform within the
screen.
Cycle Area : The area of the first period of waveform on the screen and
the unit is voltage-second. The area above the zero reference (namely the vertical
offset) is positive and the area below the zero reference is negative. The area
measured is the algebraic sum of the area of the whole period waveform.
Note: When the waveform on the screen is less than a period, the period area
measured is 0.
How to Measure with Cursors
Push the Cursor button to turn cursors on and display the cursor menu. Push it
