– Increments (clockwise direction) or decrements (counterclockwise direc-
tion) the instrument parameter at a defined step size in the case of a
numeric entry
– 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.
Settings controls
Alternative methods for setting parameters:
●
Rotary knob, Arrow keys
The rotary knob and arrow keys also enable you to set nominal values by:
– Navigating to the corresponding parameter and activating the edit mode
– Increasing or decreasing the value.
Note:
If you enter the voltage or current limit value using the rotary knob, the
R&S
HMP immediately applies the set value. You can terminate the entry by
pressing the corresponding key, e.g. Voltage, but for these parameters, the
instrument also exits the setting mode after the fallback time has elapsed.
See the user manual, chapter Instrument Functions > General Functions >
Key Fallback Time .
Settings in menus are not affected by the fallback time. Either you confirm a
setting, or return using the arrow keys.
●
Numerical Keypad (R&S HMP40x0 only), enables you to:
– Directly enter values ("0...9")
– Insert a decimal point (".")
– Delete a value ("C")
Note:
If you enter a value using the keypad, you must press Enter to confirm
your entry. Otherwise, the instrument disables the edit mode without the
changes taking effect.
