2.3.5 Numeric Control Usage
The numeric control is used to adjust the value and units. Whenever you bring the
mouse pointer over the numeric control, a tooltip appears which shows the possible
values in that range.
Figure 9: Tooltip showing possible values in the range
The numeric controls can be used in the following ways:
Use the up/down arrows to change the value. The control automatically stops at the
maximum/minimum allowed value.
You can increase or decrease the value starting at a specific portion of the value. To do
this, place the cursor to the right of the targeted digit and use the up/down arrows. This
is especially useful when changing a signal characteristic that is immediately
implemented, and observing the result in another instrument. For example, you can
change the signal generator’s frequency by increments of 10 MHz and observe the
measured result in a signal analyzer:
Figure 10: Typing directly into the field
Type directly into the field and press the Enter key. If you enter a value outside the
allowed range, the control automatically limits the entered value to the maximum or
minimum allowed value.
When you type the value, you can type the first letter of the allowed unit of measure to
set the units. For example, in the Frequency control you can use "H", "K", "M", or "G" to
specify hertz, kilohertz, megahertz, or gigahertz, respectively. (The control is not case
sensitive.)
The controls allow scientific notation if it is appropriate to the allowed range. Type the
first decimal number, enter an "E", and omit any trailing zeroes. For example, in the
Frequency control you can type 2.5e+9 and press [Enter] to set the frequency to
2.5 GHz. (The plus sign is automatically inserted if it is omitted.)
