Understanding Oscilloscope Functions
If the signal yo
u are viewing is also the trigger source, use the graticule or the
cursors to estimate the frequency of the displayed waveform. Compare this to
the Trigger Frequency readout in the lower right corner of the screen. If they
differ by a large amount, you may have aliasing.
The next table lists the time base settings that you can use to avoid aliasing at
various frequencies and the respective sample rate. At the fastest Horizontal Scale
setting, aliasing is not likely to occur due to the bandwidth limitations of the
oscilloscope input amplifiers.
