Table 2-3: Keys on the keypad
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
(G/n dBμV, M/μ μV, k/m mV and
x1 dB(m))
These keys add the selected unit to the entered numeric value and com-
plete 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.
2.2.1.6 Navigation Controls
The navigation controls include a rotary knob, navigation keys, and the display keys.
They allow you to navigate within the display or within dialog boxes.
Rotary Knob
The rotary knob has several functions:
●
Increments (clockwise direction) or decrements (counterclockwise direction) the
instrument parameter at a defined step width in the case of a numeric entry.
●
Moves the selection, e.g. to a function block in the block diagram
●
Shifts the selection bar within focused areas (e.g. lists).
●
Acts like the [Enter] key, when it is pressed.
Editing Keys
Editing keys enable you to confirm an entry, delete individual characters, or exit the
current operation.
