Reducing Trace Noise
Reducing Trace Noise
Any of the following methods can be used to lower the trace noise.
•
Turning on sweep averaging
•
Turning on smoothing
•
Narrowing the IF bandwidth
For more about sweep averaging and the IF bandwidth, see “Turning on Sweep Averaging”
on page 395 and “Narrowing the IF bandwidth” on page 394.
Turning on Smoothing
Smoothing can be used to reduce noise that has relatively small peaks. By turning on
smoothing, the value of each point on a trace is represented by the moving average over the
values of several nearby points. The smoothing aperture (percentage of sweep span)
defines the range of points to be included in the calculation of the moving average.
NOTE
You can define the smoothing trace by trace.
