A typical application of the Low pass filter I/O is to remove unwanted higher frequency noise from a measurement, which may negatively affect further operations on the measured data.
Note:
As of Multi Channel oscilloscope software version 1.43.0, the Low Pass filter I/O is no longer available in the software for new setups
and measurements.
Use the Filter I/O instead.
Existing saved setups containing the Low Pass Filter I/O can be loaded and used.
Properties
To control the behavior of the Low pass filter I/O, several properties are available. These can be accessed through a popup menu which is shown when the I/O is right clicked.
Frequency
The Frequency property sets the cut-off frequency of the filter, the point where the amplitude of the signal is reduced by -3 dB. Several standard values are available, as well as a user defined setting.
Gain
A Gain property is available to apply an optional gain to the filter. Several standard values are available, as well as a user defined setting.
