or continuous steps.
As an example, we shall adjust the carrier frequency using the rotary control for continuous
adjustment as well as in selected increments/decrements using single steps.

to select carrier frequency as the current function. The frequency is displayed as
100.000 000 MHz. The number of digits behind the decimal point shows the maximum
resolution: the frequency can be changed in 1 Hz steps.
Using rotary control
1 Select rotary control adjustment by toggling the
KNOB/
STEP
key so that a bracket underlines the
carrier frequency. With the bracket displayed, the control knob is enabled and its
sensitivity can be set.
2 Adjust rotary control sensitivity by pressing either the
x10
key or the
10
key. Pressing
the
10
key increases the length of the bracket by one decimal place. Pressing the
x10
key
shortens the length by one decimal place. In this way, rotary control resolution decreases or
increases by a factor of ten.
