Fluke 196C Displaying Glitches, Suppressing High Frequency Noise, Select Glitch Detect On

Using The Scope	1
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
	menu.

3	Select Glitch Detect: On
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 Glitch Detect to Off 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
	menu.

3	Select Glitch Detect: Off, then
	select Average: On to open the
	Average menu
4	Select 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”.
