Type of key
Description
Alphanumeric keys
Enter numbers and (special) characters in edit dialog boxes.
Decimal point
Inserts a decimal point "." at the cursor position.
Sign key
Changes the sign of a numeric parameter. In the case of an alphanu-
meric parameter, inserts a "-" at the cursor position.
Unit keys (GHz/-dBm MHz/
dBm, kHz/dB and Hz/dB)
Adds the selected unit to the entered numeric value and complete the
entry.
In the case of level entries (e.g. in dB) or dimensionless values, all units
have the value "1" as multiplying factor. Thus, they have the same func-
tion as an ENTER key.
