The measurement picture can be organized to show the measurements the way you want them. The full screen can be used to show one type of result presentation, either graphically or numerically. This is called a
Single View
Alternatively the screen can be divided in two halves and each of them can show results independent of the other graph. This is called
Dual View
Usually the two graphs are connected so the data cursor handling can affect both graphs. This is especially useful if both a level versus time and a level versus frequency display are on the screen simultaneously or if the screen is divided to show both a graphical and a numerical version of the same data. We call this
Connected Views

Measurement display properties (like displayed functions, dynamic range and full scale) are selectable directly in the measurement pictures. Tap on the graph and the available menus and selections will be displayed.

A number of small Icons are located on the
Instrument Status Bar at the top of the display.

At the bottom of the screen there are four buttons. These buttons help you to add information, annotation and comments to your measurements.
