1.2.2 Confirming and Cancelling Entries
Depending on the input you have made, there are several ways to confirm entries.
● Values without unit or values that have a fixed unit that you enter in an input field
can be confirmed with the ENTER key or by pressing the center of the rotary knob.
Alternatively, you can confirm such an entry by pressing the softkey that has
opened the input field in question.
● Values that have flexible units, like frequency or time, can be confirmed with one of
the unit keys.
If you confirm a such a value with the ENTER key, the R&S FSH always uses the
smallest possible unit (e.g. Hz).
● If you have opened a submenu or input field by accident, you can close it without
making any changes with the CANCEL key.
1.2.3 Using the Rotary Knob
Using the rotary knob, you can do several things.
● The rotary knob works like a cursor key in dialog boxes or softkey submenus. In
that case you can navigate to one of the items with the rotary knob. If the dialog
box covers more than one screen page, it also scrolls through the dialog box.
Turning it to the right corresponds to a downward movement. Moving it to the left to
an upward movement.
● The rotary knob increases or decreases any kind of numeric value if an input field
is active.
Turning it to the right corresponds to an increase, turning it to the left to a decrease
of a numeric value.
In most cases, the rotary knob changes numeric values with a fixed step size.
● The rotary knob moves markers around.
Again the step size is fixed.
● Pressing the rotary knob has the same effect as pressing the ENTER key as it
confirms an entry or selection.
