Application Examples

clearly.

See the figure below for better understanding.

Eliminating Random Noise

Press the ACQUIRE button to see the Acquire menu.

Push the Type option button and select Real Time.

Push the Average option button.

Push the Averages option button and adjust the number of running averages to watch the
change in the waveform display.

Note: Averaging reduces random noise and let you view the signal details more easily.
