Dialog Elements in the Menu 
This section describes the various types of dialog fields and the procedure for the input of values and 
parameters.  
 
In many input or select field types, a selection made must be confirmed using the ENTER key. The cursor can be 
freely shifted over these fields; only after confirmation is the setting transferred to the instrument software. 
In the case of select fields without confirmation, settings take effect immediately with the cursor selection. 
 
 
 
Input Fields 
An input field (editor) is a white, rectangular area on the screen which permits numbers or characters to 
be entered. Input fields are available both in measurement and in popup menus. In graphical 
measurement menus, the input fields are popup windows which can be called up by means of hotkeys 
while the instrument is in the function mode. 
 
Note:  The easiest and quickest way to enter numbers or characters is by means of an external 
keyboard that is connected to the KEYBOARD connector at the rear of the CMU (see 
Chapter 1). Alternatively, follow the directions given in the next two sections.  
 
 
 
Input of Numbers 
Input fields for numerical values are activated by pressing the respective softkey. Numerical values can 
either be varied using the rotary knob (by incrementing/decrementing individual digits) or directly 
entered via the numerical keypad (DATA) on the front panel or an external keyboard. To this end, the 
insert and overwrite mode is available. It may be necessary to confirm the input for transfer to the 
instrument hardware.  
In the following, the most important possible inputs using the rotary knob or the numerical keys will be 
described. 
 
 
 
 
 
 
Activating an input field and a digit 
%  To activate the input field press the associated softkey. 
The input field appears with a blue frame. The symbol for the 
rotary knob appears at the top right of the input field. 
The input field is in start mode, indicated by a small white 
triangle on a gray background. From the start mode, it can be 
switched to either insert or overwrite mode.  
 
 
 
 
 
 
Input using the rotary knob – Overwrite mode 
%  In the start mode, turn the rotary knob to activate the overwrite 
mode and vary the last digit of the current number. 
%  Use the left 
 or right   cursor key to switch between the 
decimal places of the indicated number. 
% Increment/decrement the active digit by turning the rotary 
knob. 
The individual digits can be varied without restriction. 
Incrementing a “9“ produces 0 and causes the next higher
