3.16.7 Zoom
For complicated waveforms with more waveform points, it’s difficult to show the fine part
s of the waveform in a limited display window. Therefore, the functions of zoom and shif
t are required to locally according to the zoom ratios so as to clearly display the fine par
ts of the waveform.
For example, zoom and shift the Sine with 1000 points.
Firstly insert a Sine with 1000 points and amplitude 1Vpp.
Use point edition function to modify X-coordinate to 402 points and the Y-coordinate to 4
V. Modify X-coordinate to 251 points and the Y-coordinate to 550mV. The two waveform
points that’s just modified cannot be seen in the display window because the resolution o
f the display window is lower.
