Trace zoom
Trace zoom in spectrum analyzer mode allows you to view close-up and full-span
spectrum simultaneously in two separate windows. This is useful for looking into the
details of high-density signals by zooming into a sub-band of a wide span.
In this demonstration, we will use the trace zoom function look more closely at a signal
and peak search in the zoom span only.
Trace Zoom Demo Instructions for MXE Keystrokes
Turn on trace zoom [View/Display], {Trace Zoom}
Move zoom block around the signals of
interest
Change zoom span to focus on the signals of
interest only
Put a marker on the signal of interest
Observe the signals in both windows

Did you know?
Zone span is different from trace
zoom. Zone span can set different
RBW, VBW, and sweep times for
signals with only one active window.
Trace zoom makes two windows
active simultaneously and requires
that both windows use the same
bandwidths and sweep times.
