Apparent signal due to aliasing
(2) Aliasing distortion
・
If the frequency of signal being measured is significantly
higher than the sampling rate, it is possible for sampling
to produce an apparent signal which is actually non-
existent.
・
Aliasing distortion cannot be avoided with methods of
measurement, like the Memory recorder function mode, in
which the sampling period for the time axis range may
vary widely.
・
Because the measurement limit frequency (refer to next
page) is determined by the time axis range used for
measurement, try to use as high speed a range as possible
for performing measurements.
・
When measuring a repeating signal, using the auto
ranging function is another useful technique. Refer to
Section 6.4, "Auto Range Function".
