Measuring Multiple Signals
Comparing Signals on the Same Screen Using Marker Delta
5 Place a marker at the
highest peak on the display
(10 MHz).
• Press Peak Search.The Next Pk Right and Next
Pk Left softkeys are available
to move the marker from peak
to peak. The marker should be
on the 10 MHz reference
signal.
6 Anchor the first marker
and activate a second delta
marker.
• Press Marker, Delta. The symbol for the first marker
is changed from a diamond to a
cross with a label that now
reads 2, indicating that it is the
fixed marker (reference point).
The second marker symbol is a
diamond labeled 1Δ2,
indicating it is the delta
marker. When you first press
the Delta key, both markers are
at the same frequency with the
symbols superimposed over
each other. It is not until you
move the delta marker to a new
frequency that the different
marker symbols are easy to
discern.
7 Move the delta marker to
another signal peak.
• Press Peak Search, Next Peak. The amplitude and frequency
difference between the
markers is displayed in the
marker results block of the
screen. Refer to the upper right
portion of the screen.
See Figure 2-2.
