Description

1

Status indicator

Indicates whether the signal is running or waiting for a

trigger.

2

Functional block

Represents a basic task in signal generation.
The push button provides access to any number of asso-

ciated actions to accomplish the task.
The On/Off (checkbox) and the block label quickly acti-

vates the basic task.

3

Control signal block

Indicates information on the control signals like signal

content, input or output and provides quick access to the

corresponding configuration dialog.
A dedicated control block is displayed for the baseband

block (3a) and RF block (3b).

4, 6

Signal lines (digital, ana-

log)

Show the currently configured signal flow.

Thick lines represent the digital I/Q streams, see (4)
in the figure above

Thin lines represent the analog signals (6)

5

Graphics indicator

Denotes that the signal is displayed graphically (5a/5b).

7

Connector icons

Represent the interfaces for signal input and output.

RF signal connector output (7a)
Icons vary depending on the frequency.

Analog I/Q signal connector output (7b)

Digital I/Q signal connector input (7c)

8

Stream indicators

Show the input streams at the I/Q stream mapper.

Taskbar

The "Taskbar" contains labeled softkeys and minimized views (thumbnails) of
active graphics and dialogs.

Initially, it shows the permanently assigned softkeys. The softkey with the sine
wave denotes that no signal is activated for graphical representation.

Figure 7-2: Taskbar in default state

Whenever you open a settings or graphics dialog, it is automatically assigned to
the "Taskbar". The softkeys shown in the following figure represent the variants.
