Figure 4-6: Input keys
The input keys only have an effect when any kind of input field is active on the display.
There are several types of input keys.
●
Alphanumeric keys
The alphanumeric keys allow you to enter numeric values or characters: the num-
bers from 0 to 9, the alphabet, a minus and plus sign and a dot. Pressing the num-
ber 0 repeatedly allows you to enter an empty space and an underscore.
Press the corresponding key to enter a numeric value. In case of numeric values,
each key covers just the number that is printed on it. You can enter negative val-
ues with the minus sign key and enter values that contain decimal places with the
dot key.
Example: Press the "Freq" key and select the "Center Frequency" menu item.
Enter a number with the alphanumeric keys.
If you need to enter a character (for example for file names), the key assignment
changes. Each key covers one number and more than one character with the first
choice being a lower case character. If you need to enter a character, press the
key several times until the character you require is selected.
Example: Press the "Freq" key and select the "User Preference" menu item. In the
dialog box, select the "Site Name" menu item and enter some characters (for
"Home", for example, press 6x"4", 3x"6", 1x"6" and 2x"9").
●
Unit keys
The unit keys confirm entries of values that have a unit. The units assigned to each
key are indicated on the key itself or next to the key.
Example: Press the "Freq" key and select the "Center Frequency" menu item. To
define a center frequency of 100
MHz, enter "100" and confirm with the MHZ key.
●
Escape key
The "Esc" key cancels entries and closes the input field. The firmware does not
adopt the entry you have made.
●
Backspace key
The "Backspace" key ( ) moves the cursor one position backwards and deletes
the character / number that was in that place.
Tip
: If an input field is visible, the backspace key toggles between the last two
entries. Using this feature, you can, for example, quickly toggle between two center
frequencies.
●
"Enter" key ("
✓
")
The "
✓
" key confirms an entry you have made.
If you confirm a value that has a unit with the "
✓
" key, the R&S
FPC1000 always
uses the highest possible unit (for example GHz or s).
In addition, the group of input keys also contains cursor keys and the rotary knob.
