1.2.1 Using the Alphanumeric Keys
Using the alphanumeric keys, you can enter numeric values or characters. The
alphanumeric keys include the numbers from 0 to 9, the alphabet, a minus sign and
dot.
If you have to enter a numeric value, press the corresponding key. In case of numeric
values, each key covers just the number that's printed on it.
You can enter negative values with the minus sign key and enter values that contain
decimal places with the dot key.
If the R&S FSH asks you to enter a character or you need to enter a character (e.g. file
names), the key assignment changes. Each key covers one number and more than
one character with the first choice being a character. If you need to enter a character,
press the key several times until the character you require is selected. The following
table shows an overview of character assignment.
You can correct entries with the BACK key. The BACK key moves the cursor one
position backwards and deletes the character that was in that place.
