Step/Knob Ratio
This softkey sets the ratio between the increment value of the step keys
and the front panel knob. For example, if you set the increment value
for frequency to 1 MHz and set the step/knob ratio to 10/1, when
frequency is the active function the up and down arrow keys will
change the frequency in 1 MHz steps and the front panel knob will
change the frequency in 1/10th of 1 MHz steps. This ratio only applies
when you have a function active that has an associated increment
value.
When you press
Step/Knob Ratio the number displayed in the active entry
area represents the arrow keys step size in the ratio. To enter a new
value, rotate the front panel knob until the desired value is displayed,
use the up and down arrow keys, or enter the value using the numeric
keypad and press the
Enter terminator softkey.
The step/knob ratio is a persistent state; it is not affected by an
instrument preset or by a power cycle.
