front panel of the instrument.

Cursor Up/Down buttons for data variation and a step symbol , and a Close button. Besides it is
closed automatically as soon as an active display element in the diagram area is clicked or a new menu
command is activated.
Display Formats and Diagram Types
A display format defines how the set of (complex) measurement points is converted and displayed in a
diagram. The display formats in the
Trace – Format menu use the following basic diagram types:
•
Cartesian (rectangular) diagrams are used for all display formats involving a conversion of the
measurement data into a real (scalar) quantity, i.e. for
dB Mag, Phase, Delay, SWR, Lin Mag,
Real, Imag and Unwrapped Phase.
•
Polar diagrams are used for the display format Polar and show a complex quantity as a vector
in a single trace.
•
Smith charts are used for the display format Smith and show a vector like polar diagrams but
with grid lines of constant real and imaginary part of the impedance.
