Frequency Keys
Pressing the
[MI+M~/SWEEP)
key turns markers Ml and
M2
on, and sweeps
between the two markers.
This function toggles marker sweep mode on and off. If marker sweep mode
is off when this key is pressed, the mode is turned on and the
Ml-M2
SWP
LED annunciator is turned on. Markers Ml and
M2
are turned on if they were
previously off, and the instrument sweeps from a start frequency of marker
Ml to the stop frequency of marker
M2.
NOTE
If the value of Ml is greater than the value of
M2,
their values will be interchanged when they are
put into the start and stop frequencies.
In this mode, the FREQUENCY display shows Ml as the start frequency
and
M2
as the stop frequency. The START, STOP, CF and SPAN values
are coupled with markers Ml and
M2.
That is, any change in the values
of START and STOP frequency will directly alter the values of markers Ml
and
M2,
and vice versa. If the frequency of marker Ml or
M2
is the active
parameter displayed in the MARKER/SWEEP/STATUS area, and if its value is
changed, or if new START, STOP, CF, or SPAN frequencies are entered, then
both
the FREQUENCY and the MARKER/SWEEP/STATUS displays are updated
simultaneously to the new value.
When marker sweep is toggled off, by pressing
CMI+M~/SWEEP)
again, the
START, STOP, CF and SPAN values will revert to what they had been before
marker sweep was turned on. The
Ml+M2
LED annunciator will be turned
off, but Ml and
M2
will remain on.
