7.2Means of Manual Interaction
For the manual interaction with the R&S AREG, you have several methods that
you can use as an alternative to perform a task:
●
Touchscreen:
Touchscreen operation is the most direct way to interact. Almost all control
elements and actions on the screen are based on the standard operating system concept. You can tap any user interface element to set parameters in dialog boxes, enter data, scroll within a dialog etc., as if you work with a mouse
pointer.
Tapping the screen works like clicking mouse buttons:
–Touch quickly = click: Selects a parameter or provokes an action.
–Touch and hold = right-click: Opens a context-sensitive menu.
–Touch and swipe = drag: Scrolls through the contents of a display element
larger than the screen, e.g. a list or a table.
●
Function keys and rotary knob:
The front panel provides nearly all functions and controls to operate the instrument in the classic way, without touchscreen.
●
Optional mouse and/or keyboard:
These devices work like known from PCs. The navigation keys on the front
panel correspond to the keys on the keyboard.
This manual describes the manual interaction with the instrument via the touchscreen. It mentions the alternative methods using the keys on the instrument or
the on-screen keypads if it deviates from the standard operating procedures. The
usage of the touchscreen and navigation keys is described in Chapter 7.4,
"Accessing the Functionality", on page 44.
Throughout the manual, the term "select" refers to any of the described methods,
i.e. using a finger on the touchscreen, a mouse pointer in the display, or a key on
the instrument or on a keyboard.
