Measure System
The oscilloscope displays the voltage in relation to time and tests the
waveform displayed. Different measurement techniques such as scale,
cursor, and auto measure modes are used.
Scale Measurement
This method allows you to make a quick visual estimate. For example, you
might look at waveform amplitude and determine that it is a little more than
100 mV. You can take simple measurements by counting the major and
minor graticule divisions involved and multiplying by the scale factor. For
example, if you counted five major vertical graticule divisions between
minimum and maximum values of a waveform and knew you had a scale
factor of 100 mV/div, then you could easily calculate your peak-to-peak
voltage as follows:
5 divisions x 100 mV/div = 500 mV
Note: When the display type is set to Vector, the oscilloscope
connects the sample points by using digital interpolation.
Interpolation mode contains linear interpolation and sin(x)/x
interpolation. Sin(x)/x interpolation is suitable for reconstructing
curved or irregular wave shapes, especially when the sample rate is 3
to 5 times the system bandwidth or at faster time base settings.
