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:

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:
