IDA - 3106 Narda
Tracking the peak values (Peak Tracking)
The Peak Tracking function allows you to track a traveling peak value that
you previously determined using a Peak softkey (e.g. Highest Peak). The
marker cannot track frequency jumps or rapidly changing peak values. In
contrast, the marker is always set to the highest peak when you select the
Highest
setting, so it can track any jump. This function is only available in
Spectrum, Time Domain (Scope)
and
I⁄Q Analyzer
modes and is
activated (
On
) by default.
To activate and deactivate Peak Tracking:
 Press the
Peak Tracking
softkey in the
Marker
menu.

The softkey shows

The Magnifier function allows you to display a magnified view of the area
around the current marker position in a separate window (split screen). This
two stage selectable enlargement acts like a graphical magnifier, so that no
new measurement is started and no parameters are changed. The active
marker is shown in the center of the X axis of the enlarged area.
One of the great advantages of the IDA is its very high frequency and time
resolution. Using the Magnifier function, you can display and analyze both
the entire spectrum and a section of it at full resolution. This allows you to
display a magnified view of the area around the current marker position in a
separate window (split screen). This two stage selectable enlargement acts
like a graphical magnifier, so that no new measurement is started and no
parameters are changed. The active marker is shown in the center of the X
axis of the enlarged area. You can set a maximum magnification of 50 times
in the frequency domain or 500 times in the time domain.
