Navigation controls
The navigation controls include a [rotary knob] and [arrow] keys. They allow you
to navigate within a setting, menus or dialogs.
When you select a function key, e.g. the [Voltage] key, the [arrow] keys light
up, indicating that they are usable for input.
●
Rotary knob
The [rotary knob] has several functions:
– Moves the selection, e.g. to a parameter in a settings dialog.
– Activates the edit mode of a parameter.
– Increments (clockwise direction) or decrements (counterclockwise direc-
tion) the instrument parameter of a numeric entry with a defined step size.
– Acts like the [Enter] key, when it is pressed
●
Arrow keys
– Move the selection up and down, or forward and backward, e.g. to a
parameter in a settings dialog
– Return to a previous menu level ([left] arrow key)
– In a numeric entry field, increase or decrease the value, or move between
the digits.
If you enter the voltage or current limit value with the [rotary knob], the
R&S
HMP immediately applies the set value. It exits the setting mode auto-
matically, after the fallback time has elapsed, or you can manually exit the
setting mode by pressing the corresponding function key.
Settings in menus are not affected by the fallback time. Either you confirm a
setting, or return using the [arrow] keys.
