Delta Marker

MARKER

This 

 causes the difference in frequency between two markers

to appear on the synthesizer display. The frequency difference is

indicated in the following format:

Where m= the last marker activated, n= the reference marker,

and XXXXX represents some frequency value. On a CRT display,
the trace between the two selected markers is intensified. An asterisk
next to the key label indicates that this feature is active.

At preset (factory), the synthesizer is set to measure the difference
between 

 and Ml (marker reference). If markers have not

been activated after preset, selecting Delta Marker indicates the
difference between 

 and Ml. Both of these markers have an

asterisk next to their key label, indicating that they are on.

Whenever Delta Marker is selected, it reactivates the last marker
selected and makes that marker the “m” frequency. If the delta
marker feature is active, selecting a marker causes the “m” frequency
to change to the marker selected. If a frequency entry is made when
delta marker is in the active entry area, the frequency value of the

“m” frequency is changed to the new frequency entry causing the

new difference in frequency to be displayed. Negative frequency
differences are possible if “n” is greater than “m”.
