Numeric Control Usage
72
The numeric control is used to adjust the value and units. Whenever you
bring the mouse pointer over the numeric control, a tool tip appears which
shows the possible values in that range.

Tool tip 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:

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 Hz, KHz, MHz or GHz , respectively.
(The control is not case sensitive.)
