Full one-port calibration (SOL) is used for reflection coefficient measurements (S11). The three calibration standards (SHORT, OPEN, LOAD) are measured (See figure below) in the process of this calibration. Measurement of the three standards allows acquisition of all the three error terms (Ed, Es, and Er) of a one-port model. Full one-port calibration is a highly accurate method for 1-port reflection measurements.
Before starting calibration perform the following settings: select active channel, set the parameters of the channel (frequency range, IF bandwidth, etc.), and select the calibration kit.

To open full one-port calibration submenu, use the following softkeys: Calibration > Calibrate > Full 1-Port Cal |
|
Connect SHORT, OPEN, and LOAD standards to the selected test port in any consequence as shown in the above figure. Perform measurements clicking the softkey Open, Short, Load corresponding to the connected standard. During the measurement, a pop up window will appear in the channel window. It will have Calibration label and will indicate the progress of the measurement. On completion of the measurement, a checkmark will appear in the left part of the softkey. |
|
To complete the calibration procedure, click Apply. This will activate the process of calibration coefficient table calculation and saving it into the memory. The error correction function will also be automatically enabled. |
|
To clear the measurement results of the standard, click Cancel. This softkey does not cancel the current calibration. To disable the current calibration, turn OFF the error correction function (See Error Correction Disabling). |

note |
The calibration status can be checked in channel status bar (See General error correction status table) or in trace status field (See Trace error correction status table). |
