Using Average, Persistence and Glitch Capture

Displaying Glitches

To capture glitches on a waveform, do the following:

1						Display the SCOPE key labels.



2						Open the Waveform Options
2						Open the Waveform Options
						menu.
						menu.

3					Select Display Glitches: Yes

4 Exit the menu.

You can use this function to display events (glitches or other asynchronous waveforms) of 50 ns (nanoseconds) or wider, or you can display HF modulated waveforms.

Suppressing High Frequency Noise

Switching Display Glitches to No will suppress the high frequency noise on a waveform. Averaging will suppress the noise even more.

1						Display the SCOPE key labels.



2						Open the Waveform Options
2						Open the Waveform Options
						menu.
						menu.

3						Select Display Glitches: No,
						then select Average: to open the
						then select Average: to open the
						Average menu


4						Select Average: Normal, and
						Factor : 8x
						Factor : 8x

Tip

Glitch capture and average do not affect bandwidth. Further noise suppression is possible with bandwidth limiting filters. See Chapter 1: “Working with Noisy Waveforms”.
