16 3: The Screen and Basic Concepts
3.4 Parameters, Input Components and Editors
This section explains the possible parameter types and cross references an example of each. The
components which represent them, and how each type can be modified using the softkey interface,
a mouse or a keyboard, are detailed in the section referenced by each type.
Parameters fall into these categories:
“3.4.1 Numeric Parameters” on page 16 such as:
• Network interface port numbers
• The frequency counter’s user-specified reference frequency
“3.4.2 Mutually Exclusive Options” on page 18 such as:
• Print job destination
• TCP/IP address assignment method
3.4.1 Numeric Parameters
Numeric parameters fall into two categories:
Those confined to the integer domain.
Those in the real number domain such as the frequency counter’s reference frequency and
test mask points’ x and y coordinates.
All numeric parameters can be set as described in “3.4.1.1 The Number Pad Editor” on page 17.
Those in the integer domain can also be set as described in “3.4.1.2 The + and - Integer Parameter
Interface” on page 18. Numeric parameters are presented using the following components which
can be directly manipulated with the mouse or keyboard as described in Figure 5.
Figure 5: Spin Buttons
When a mouse or keyboard is not available, parameters presented by spin buttons must be set
using one of the editors described in the following sections. The editors can be used if you prefer
using them over the alternative input methods.
Spin Button
Click to increase value
Click to decrease value
Mouse Interface
Right-click for menu of frequently used values.
(Not all parameters provide menus.)
Using a keyboard you can
type directly into the field to
avoid using the number pad
editor.
