M2 as the reference. Watch the displaychange to indicate:
--> DELTA MKR (3-2) : 1200.000000 MHz
You can choose any of the ve 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 dierence b etween the frequencies is
negative and is displayed as suchby the swept signal generator. The
CRT display continues to intensify the dierence 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
dierence change. The last active marker (in this case, marker 3)
changes frequency value, not the reference marker.
