Measuring Multiple Signals
Comparing Signals on the Same Screen Using
Marker Delta Pair
In this procedure, the analyzer 10 MHz signal is used to measure
frequency and amplitude differences between two signals on the same
screen using the delta pair marker function.
Step 1. Refer to the previous procedure Comparing Signals on the Same
Screen Using Marker Delta on page 12 and follow steps 1, 2 and 3.
Step 2. Turn on Delta Pair reference marker to compare the 10 MHz signal and
the 30 MHz signal:
Press
Peak Search, Marker, Delta Pair (ref).
Note that the
Delta Pair marker does not anchor the first marker.
Step 3. Use the knob or Peak Search to move the second marker (labeled 1) to
the 30 MHz peak:
Press
Peak Search, Next Peak or Next Pk Right.
Step 4. Use the front panel knob to move the ref marker to the 20 MHz peak:
The active function displays the amplitude and frequency difference
between the 20 MHz and 30 MHz peaks as shown in Figure 2-3.

NOTE In Figure 2-3 notice that the active function readout has moved to the
top left of the analyzer display. The active function position has three
positions: top, center and bottom. To modify the active function position:
Press
Display, Active Fctn Position, Top (Center, or Bottom).
Center position is the factory default setting.
