Interpolation
Selects the interpolation method.
If the defined sample rate ("Sample rate") is higher than the ADC sample rate, interpo-
lation adds points between the captured samples of the waveform by various mathe-
matic methods. The selected interpolation method is also used for zooming.
"Linear"
Two adjacent ADC sample points are connected by a straight line, the
interpolated points are located on the line. You see a polygonal wave-
form similar to the real signal, and also the ADC sample points as
vertexes.
"sin (x)/x"
Two adjacent ADC sample points are connected by a sin(x)/x curve,
and also the adjoining sample points are considered by this curve.
The interpolated points are located on the resulting curve. This inter-
polation method is precise and shows the best signal curve.
"Sample/Hold"
The ADC sample points are displayed like a histogram. For each
sample interval, the voltage is taken from the sample point and con-
sidered as constant, and the intervals are connected with vertical
lines. Thus, you see the discrete values of the ADC - the measured
samples.
