9. Enter the delta-marker mode and place the active marker just to the right of
the harmonic at 400 MHz.
10. Select item 6, MARKER START/STOP, from the Marker/Frequency menu.
The spectral display reappears and brackets the calibration signal third and
fourth harmonics. The marker start/stop selection automatically adjusts the
starting frequency of the display and the span/div so that what is displayed is
what was between the markers. If you are not in the delta-marker mode when
you select MARKER START/STOP, the 2715 will enter zero span at the
current center or marker frequency.
11. Turn off the markers. Notice that the resolution BW has also changed in
response to the changed span/div, because RES BW was in AUTO mode.

Suppose you want to measure the difference in frequency between the peaks at
300 MHz and 500 MHz and between 500 MHz and 200 MHz. The following
steps show how to make these measurements:
12. Enter marker mode, and position the marker on the 300 MHz peak.
13. Enter delta-marker mode and place the active marker on the 500 MHz peak.
The difference is 200 MHz.
14. Select item 5, TRANSPOSE MARKERS, from the Marker/Frequency menu.
15. Turn the FREQ/MKRS knob.
The movable marker has become the reference and the old reference is now
the movable marker.
16. Move the marker to the 200 MHz peak and note the frequency difference.
17. Exit from delta-marker mode.
