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 for 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.
Full One-Port Calibration for 1-port VNA
To perform full one-port calibration, use the softkey Calibration in the left menu bar. Connect an OPEN, a SHORT and LOAD standards in any sequence to the test port as shown in above. Perform measurement using Open, Short or Load softkey respectively.
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, the left part of the Open, Short or Load softkey will be color highlighted.
To complete the calibration procedure, click Apply softkey. This will activate the process of calibration coefficient table calculation and saving it into the memory. To clear the measurement results of the standards, click Cancel softkey. This softkey does not cancel the current calibration. To disable the current calibration, turn off the error correction function (See Error Correction Disabling). |
Full One-Port Calibration for RNVNA
To perform full one-port calibration, use the softkey Calibration in the left menu bar. Then click on the Calibration Type field. In the dialog Calibration Type select Full 1-Port Cal. Complete the setting by clicking Ok.
In the dialog Calibration assign a signal source port, click on the Source Port field.
Connect an OPEN, a SHORT and LOAD standards in any sequence to the test port as shown in above. Perform measurement using Open, Short or Load softkey respectively.
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, the left part of the Open, Short or Load softkey will be color highlighted.
To complete the calibration procedure, click Apply softkey. This will activate the process of calibration coefficient table calculation and saving it into the memory. To clear the measurement results of the standards, click Cancel softkey. This softkey does not cancel the current calibration. To disable the current calibration, turn off the error correction function (See Error Correction Disabling). |

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). |
