Three methods of setting signal parameters are offered:
numeric keypad, knob and the arrow buttons. Please use
the soft menu keys for selecting the respective menu item.

The simplest method of en-
tering parameters quickly

the numerical keyboard with
the number keys (0...9), the
decimal point key (.) and the
minus key (-). When entering
parameters via the keyboard
the value will be accepted

unit key GHz (-dBm), MHz
(dBm), kHz (dB..) or Hz (dB..).
The keys have multiple as-
signments. Prior to pushing
any key an entry may be de-
leted by pushing the key BACK. During the operations the
window will remain open. The CANCEL key will termi-
nate the entry of parameters and close the window. In text
mode characters can be confirmed with the ENTER key.
5.2 Rotary knob
It is possible to only use the knob for all settings. Va-
lues can also be entered with the rotary knob. The entry
is changed in steps and the spectrum analyzer immedia-
tely sets the appropriate entry parameter. Turning the knob
