Working with Noisy Waveforms
To suppress high frequency noise on waveforms, you can
limit the working bandwidth to 20 kHz or 20 MHz. This
function smoothes the displayed waveform. For the same
reason, it improves triggering on the waveform.
To choose HF reject on for example input A, do the
following:
1 Display the

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

Using the Scope and Meter
Using Mathematics Functions +, -, x, XY-mode
You can add (+), subtract (-), or multiply (x) two
waveforms. The test tool will display the mathematical
result waveform and the source waveforms.
The XY-mode provides a plot with one input on the
vertical axis and the second input on the horizontal axis.
The Mathematics functions perform a point-to-point
operation on the involved waveforms.
