Recorder Mode
Rise Time :
Displays the rise time of a waveform displayed within a cursor-defined range of
waveform data. The calculation of the rise time varies with the direction of the
cursors.
When the cursors are in the time axis direction
After determining the maximum and minimum values within a cursor-defined
range of data, the target waveform is that which first passes their mid-point
value. Assuming that the minimum and maximum values are respectively 0%
and 100%, the Rise Time is calculated within the range of 10% to 90%.

Fall Time :
Displays the fall time of a waveform displayed within a cursor-defined range of
waveform data. The calculation of the Fall Time varies with the direction of the
cursors.

After determining the maximum and minimum values within a cursor-defined
range of data, the target waveform is that which first passes their mid-point
value. Assuming that the maximum and minimum values are respectively 100%
and 0%, the Fall Time is calculated within the range of 90% to 10%.

Average :
Displays the purely arithmetic mean of data points within a cursor-defined range.
Area :
Displays the area within the cursor-defined range. When this parameter is
selected, a sub-menu for specifying the calculation method is displayed. There
are four methods as described below.
Y-T Mode
Normal : Sets the area of the cursor-defined range of data as the difference
between respective areas of the positive and negative domains,
centering on the baseline (0 V) of measured data.

- domains
+ domains
Positive :
Sets the area of a cursor-defined range of data as the total sum of
positive domains, centering on the baseline (0 V) of the measured data.
