4.5 Sampling Mode
The oscilloscope only supports real-time sampling. In this mode, the oscilloscope samples and displays
waveforms within a trigger event. The maximum real-time sample rate is 1GSa/s.
Press the
button to stop the sample. The oscilloscope will hold the last dislplay and the button led
will turn red
. At this point, you ca still use the vertical control and horizontal control to pan and zoom
the wavefrom.
4.6 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.
The interpolation method is a processing method to “connect all the sampling points”, and using some
points to calculate the whole appearance of the waveform.
The interpolation method is used for real-time sampling to fill out the gaps between points and reconstruct
an accurate waveform.
To set interpolation:
1. Press the
button.
2. Press the
softkey to select

3. Press the
softkey to toggle between
Sin(x)/x
and
x
interpolation.
