Type of key Description
Sign key Changes the sign of a numeric parameter. For an alphanumeric
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 complete the entry.
For level entries (e.g. in dB) or dimensionless values, all units
have the value "1" as multiplying factor. Thus, they have the
same function as an [Enter] key.

keys. They allow you to navigate within the display or within dialog boxes.
5.1.6.1 Rotary knob

●
Increments (clockwise direction) or decrements (counterclockwise direction)
numeric instrument parameters at a defined step width.
●
Moves the selection, e.g. to a function block in the block diagram
●
Shifts the selection bar within focused areas (e.g. lists).
●

the current operation.
