HP 8360 - Manual (Page 45)

Marker 1 was chosen because it is selected as the delta marker
reference. To change reference markers, select
Delta Ref .
Select as the reference. Watch the display change to indicate:
DELTA MKR (3-2) : 1200.000000 MHz
You can choose any of the five markers as a reference, but when delta
marker is on, if the reference marker has a frequency value higher
than the last active marker, the difference between the frequencies
is negative and is displayed as such by the synthesizer. The CRT
display continues to intensify the difference between the two markers.
When delta marker is showing in the active entry area, the ENTRY
area is active. Rotate the rotary knob and watch the frequency
difference change. The last active marker (in this case, marker 3)
changes frequency value, not the reference marker.
