Select Waveform Interpolation Method
Under real-time sampling, the oscilloscope acquires the discrete sample values of the
waveform being displayed. In general, a waveform of dots display type is very difficult to
observe. In order to increase the visibility of the signal, the digital oscilloscope usually
uses the interpolation method to display a waveform.
Interpolation method is a processing method to ―connect all the sampling points‖, and
using some points to calculate the whole appearance of the waveform. For real-time
sampling interpolation method is used, even if the oscilloscope in a single captures only a
small number of sampling points. The oscilloscope can use interpolation method for filling
out the gaps between points, to reconstruct an accurate waveform.
Press the

button on the front panel to enter the ACQUIRE Function menu; then
press the
Sinx/X
softkey to select
Sinx
or

.
X:
In the adjacent sample points are directly connected on a straight line. This
method is only confined to rebuild on the edge of signals, such as square wave.
Sinx:
Connecting the sampling points with curves has stronger versatility. Sinx
interpolation method uses mathematical processing to calculation results in the actual
sample interval. This method bending signal waveform, and make it produce more
realistic regular shape than pure square wave and pulse. When the sampling rate is 3
to 5 times the bandwidth of the system. Recommended sinx interpolation method.
