denotes the reference impedance of the source port (for wave quantities a
n
) or of the receive
port (for wave quantities b
n
). The reference impedances are defined in the Port Configuration
dialog.

Source Port selects one of the available test ports of the analyzer as a source of the stimulus
signal.

Format
The Format submenu defines how the measured data is presented in the graphical display.
•
dB Mag selects a Cartesian diagram with a logarithmic scale of the vertical axis to display the
magnitude of a complex measured quantity.
•
Phase selects a Cartesian diagram with a linear vertical axis to display the phase of a complex
measured quantity in the range between –180 degrees and +180 degrees.
•
Smith selects a Smith diagram to display an S-parameter or ratio.
•
Polar selects a polar diagram to display an S-parameter or ratio.
•
Delay calculates the group delay from an S-parameter or ratio and displays it in a Cartesian
diagram.
•
Aperture sets a delay aperture for the delay calculation.
•
SWR calculates the Standing Wave Ratio from the measured reflection S-parameters and
displays it in a Cartesian diagram.
•
Lin Mag selects a Cartesian diagram with a linear scale of the vertical axis to display the
magnitude of the measured quantity.
•
Real selects a Cartesian diagram to display the real part of a complex measured quantity.
