MARKER 1/DELTA Displays the reciprocal of the frequency or time
difference between two markers in the active function
block and in the upper-right corner of the display. If two
markers are on and the frequency span is greater than
0 Hz, MARKER 1/DELTA displays the difference
between the two markers in time. If two markers are on
and the frequency span is equal to 0 Hz, MARKER
1/DELTA reads the difference in frequency. You can
toggle between MARKER 1/DELTA and MARKER
DELTA without changing the position of the markers.
Front-panel key access:

MARKER DELTA Reads the difference in amplitude and frequency
