3 Manual Operation
This Chapter describes the controls, displays, etc, the screen layout and how to operate the R&S NRP.
Keys
Keys on the front panel of the meter are used to manually operate the instrument. There are several
groups of keys, each group having a different function:
Softkeys
The six softkeys are rocker switches – in other words, they
can be “rocked” backwards and forwards by pressing on
the right or left side of the key.
The softkey function is context-sensitive and is indicated by
screen labelling.
For more information on the softkeys see Menu handling
on p. 3.7 and Dialog boxes and their control elements on
p. 3.8.

The hardkeys are a direct way of activating the main func-
tions and are always available for use:
• Brightness/contrast
• Frequency entry
• Preset and setups
• Zeroing
For further information on using the hardkeys, see Chapter
4, section "Hardkeys".
Cursor keypad
The cursor-key functions are context-sensitive. They can
be used to
• Select the menu,
• Select the active window,
• Move the cursor in text boxes,
• Change the value of an entry in a text box,
• Select an element from a drop-down list,
• Adjust the brightness and contrast of the display.
With the exception of moving the cursor, the functions re-
ferred to above can also be activated using softkeys.
