Working with Noisy Waveforms

To suppress high frequency noise on waveforms, you can limit the working bandwidth to 10 kHz or 20 MHz. This function smoothes the displayed waveform. For the same reason, it improves triggering on the waveform.

To choose HF reject, do the following:

1	Display the INPUT A key labels.
2	Open the Input A menu.

3	Jump to Bandwidth.
4	Select 10kHz (HF reject) to
	accept the bandwidth limitation.

Using Waveform Mathematics Functions

When adding (A+B), subtracting (A-B), or multiplying (A*B) the input A and input B waveform, the test tool will display the mathematical result waveform and the input A and input B waveforms.

A versus B provides a plot with input A on the vertical axis and input B on the horizontal axis.

The Mathematics functions perform a point-to-point operation on waveforms A and B.

To use a Mathematics function, do the following:

1	Display the SCOPE key labels.
2	Open the Waveform Options
	menu.

Tip

To suppress noise without loss of bandwidth, use the average function or turn off Display Glitches.
