Other Parameters
•
Positive Slew Rate: On the rising edge, first calculate the difference between the
high value and the low value, then use the difference to divide the
corresponding time value to obtain the positive slew rate.
•
Negative Slew Rate: On the falling edge, first calculate the difference between
the low value and the high value, then use the difference to divide the
corresponding time value to obtain the negative slew rate.
•
Area: indicates the area of the whole waveform within the screen. The unit is V*s.
The area of the waveform above the zero reference (namely the vertical offset) is
positive, and the area of the waveform below the zero reference is negative. The
area measured is the algebraic sum of the area of the whole waveform within the
screen.
•
Period Area: indicates the area of the first period of waveform on the screen.
The unit is V*s. The area of the waveform above the zero reference (namely the
vertical offset) is positive, and the area of the waveform below the zero reference
is negative. The area measured is the algebraic sum of the whole period area.
