Ln/Lg
Logarithmic operation includes logarithm base e (ln) and logarithm base 10 (lg). In logarithmic operation, if the waveform
value is negative (the waveform is below the ground level), the result is displayed as zero.
For example: F1 =
𝑒
𝑥
, where x is the trigonometric wave function. F2 = lg (F1).

Interpolate
Between the adjacent sampling points, the waveform is interpolated according to the selected interpolation method and
interpolation coefficient. Touch
Acquire Interpolation
to set the interpolation method, and the interpolation coefficient
can be set to 2, 5, 10 or 20.
Coefficient = 2
Coefficient = 20
