get this display:

to enter 5. Then move the cursor again one position to the
right and enter 6. This will yield the desired display:
FR: 102.5600000 kHz

If the cursor as in this example is positioned below
th
the 1/100 digit turning the knob will increment
resp. decrement the value in 1/100
HINT
This allows to change values quite fast. The value is always in-
fl uenced in the digit above the cursor. So if the cursor should be
rd
positioned below the 3 digit left of the decimal point the value
would be incremented resp. decremented in 100 kHz steps. The

knob is hence well suited to enter or change values quickly,
any entry will be effective immediately.

Survey of the basic menu

After switching on and the self test the basic menu will appear
showing the last instrument set-up before switching off. The
basic menu shows the selected frequency. Also the basic
functions Sin (sine),Tri (triangle) and Sqr (square wave) can be
selected here. In order to get to the functions: positive sawtooth,
negative sawtooth, spectrum the arrow
of the menus + Rmp, –Rmp, Spc the basic functions sine, triangle
and square wave are accessible using the backspace arrow
The functions are selected via the group of pushbuttons
The function selected (Sin, Tri, Sqr, +Rmp, –Rmp) is marked with
a triangle. Selecting the function Spc a further menu is entered,
here 4 K arbitrary oder 16 K arbitrary signals and white or pink
noise are available.
