– transmission coefficient measurement mode.
8.1.4. Calibration type designation:

Factory
– factory calibration;

SOL
– one-port calibration;

SOL+T

8.2.2. Buttons for switching charts. The device screen displays buttons for quick access to four plots
with measurement results simultaneously. The chart types and their order in the row are set by the user.

– Smith chart or impedance chart;

– polar chart;

– the phase plot of the measured S-parameter, presented in the range from -180 to +
180⁰;

– S-parameter modulus (amplitude) plot on a linear scale;

– S-parameter modulus (amplitude) plot in logarithmic scale (in dB);

– voltage standing wave ratio (VSWR) plot;

– plot showing the distance to fault or discontinuity in the cable;

– plot of signal attenuation in the cable;

– group delay plot.
8.2.3. Function buttons

– expands the plot to the full screen.

–
turn off the plot to access additional settings

