FIRST-TIME USE
4-13
Using the [×÷10] and [Ø×10] keys
When you have entered a parameter value using the numerical key pad, you can adjust its value
either in single steps or continuous steps.
As an example of its use we shall adjust the carrier frequency using the knob for continuous
adjustment as well as in selected increments/decrements using single steps.
(1) Press [CARR FREQ] to select carrier frequency as the current function. Note that the
frequency is displayed as 100.000 000 MHz. The number of digits behind the decimal point
shows the maximum resolution and indicates that the frequency can be changed in 1 Hz
steps.
With the control knob
(2) Select the control knob for adjustment by toggling the [KNOB/STEP] key so that the carrier
frequency is displayed underlined by a bracket. With the bracket displayed the control
knob is enabled and its sensitivity can be set.
(3) Adjust the control knob sensitivity by pressing either the [×÷10] key or the [Ø×10] key.
Pressing the [×÷10] key increases the bracket length by one decimal place. Pressing the
[Ø×10] key shortens the bracket length by one decimal place. In this way the resolution of
the control knob is respectively increased or decreased by a factor of ten.
(4) Move the control knob in either direction and note how the displayed carrier frequency
changes by the desired amount.
(5) To check the current amount of offset from the reference carrier frequency press and hold
[TOTAL Δ]. For the duration of the key-press the offset is displayed as either a negative or
positive value.
(6) You can return at any time to the reference carrier frequency by pressing [RETN].
100.000 000 MHz is displayed.
(7) Alternatively, you can make the currently displayed frequency the reference carrier
frequency by pressing [SET REF]. Subsequently pressing [RETN] then returns you to this
frequency.
