Frequency Copying; Frequency Stepping; Deviation Limit - Motorola R-2200 Operator's Manual

3.4.1.1 FREQUENCY COPYING If the desired gener-
ator frequency is to be the same as the programmed
monitor frequency, it is not necessary to enter the fre-
quency twice. The frequency copy mode can be used as
follows:

NOTE: Shaded area indicates flashing digit. (point of
data entry)
The programmed generator is now the same as the mon-
itor frequency. In a similar manner, the monitor fre-
quency can be copied from the stored generator
frequency.
3.4.1.2 FREQUENCY STEPPING Frequency stepping
can be accomplished by using the
I

and
I

key.
First, enter the frequency programming mode by press-
ing the
B
key. The flashing digit can now be decre-
mented using the
I
6:;: )
key or incremented using the
[
~,'~
I
key. Even while the digit is flashing, the frequency
indicated on the display is the actual operating fre-
quency. It is not necessary to press
B
every time a
change is made. Frequencies are not stored in non-
volatile memory, however, until
B
is pressed. The
[I>
I
and
8TI
keys are used to position the flashing
cursor as desired.

3.4.2 DEVIATION LIMIT
The deviation alarm is set in a similar manner to frequen-
cy. Start by pressing [
~,'~
). The unit automatically switch-
es the left LCD display to view deviation alarm informa-
tion. The limit may take values between 00.0 and 99.9
kHz with 00.0 being a disable. As the 3 digits are entered
using keys 0 through 9, the blinking cursor moves to the
right automatically but may be manually moved using the
[I> I
right or
I
<liieft cursors. To clear the entire entry.
press

If the
I""' ' I
key is immediately depressed a
second time. the original number stored in memory is
displayed and the programming sequence is terminated.
The deviation alarm is provided to warn of FM deviation
levels above this preset maximum and is active in any
measurement mode provided the function switch is in the
""SENS MON"' or ""PWR MON"' position for FM type
carriers. Press
I., . . . I
to load the programmed deviation
limit. Once loaded, the left LCD display immediately
returns to the measurement mode selected prior to
programming.
