ENTERING DATA
Before proceeding to the various modes of sweep generator operation,
you need to know how to enter data from the front panel. Entering
data refers to changing a parameter’s value by editing its current
value or entering a new value to replace the current value. The follow-
ing instructions describe how to (1) open a parameter, (2) edit its cur-
rent value, and (3) enter a new value.
A typical 681XXB menu display (below) is used throughout the data
entry instructions. At this menu display, you can edit both the CW fre-
quency and the output power level parameters.
If you wish to follow along on your synthesizer, you can obtain this
same menu display by resetting your instrument (press
SYSTEM
,
then press
Reset
).
Opening the
Parameter
In order for the value of a parameter to be changed,
the parameter must first be opened.
To open the frequency parameter from the above
menu, press
Edit F1
. The menu display now
changes to show that the menu soft-key
Edit F1
has been pressed and that the frequency parameter
has been opened. An open parameter is indicated by
placing it in a window with a movable cursor under
its digits.
Only one parameter can be open at a time. If you
press
Edit L1
, then the frequency parameter will
close and the power level parameter will open.
