The main graphics area is where the measured results are displayed. The impedance magnitude and angle along with the real and imaginary parts are drawn on the polar ( circular ) grid in Ohms. The real, series resistance component is drawn in green at 0 degrees phase. The imaginary part of the series impedance is drawn in red at either +90 degrees or -90 degrees depending on the sign. A positive impedance is inductive and an negative impedance is capacitive. The combined magnitude of the total series impedance is drawn in orange and at the measured angle. | The main graphics area is where the measured results are displayed.

- | To the left of the grid the relative gain of Channel B to Channel A is displayed in dB. Next the relative phase is displayed in degrees. Next the measured frequency in Hz is displayed. Next the measured Impedance Magnitude, Angle, R series and X series are displayed. Finally the calculated capacitance ( if X series is negative ) or inductance ( if X series is positive ) is displayed. | + | To the right of the grid, the relative gain of Channel B to Channel A is displayed in dB.

At the bottom of this section, just above the ADI logo, are entry windows which allow input gain and offset calibration to be added to the channel A and B inputs. For more on the use of input attenuators please refer to the following two documents: | At the bottom of this section, just above the ADI logo, are entry windows which allow input gain and offset calibration to be added to the channel A and B inputs.
