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

Using Mathematics Functions A
±
B, AxB, A vs B
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.
