Overview
The 2-port TRL calibration function lets you measure calibration data by
connecting thru, reflection (open or short), line, or match calibration
standards to (between) 2 desired test ports. This calibration provides the
most accurate measurement for non-coaxial parts, using 12 error terms
model in total for calibration in the same way as full 2-port calibration.
Before executing TRL calibration, you need to modify the calibration kit
definition you use (or create a new one). For more information, see
Changing the Calibration Kit Definition.
Procedure
1. Press Channel Next/Channel Prev keys to select the channel for which
you want to perform the calibration.
2. Press Cal key.
3. Click Calibrate > 2-Port TRL Cal.
4. Click Select Ports, then select the test ports for which you want to
execute TRL 2-port calibration. (In the following procedure, test
ports you select here are expressed as test ports x and y.)
5. Connect the port.
Thru/Line
1. Make a THRU or Line connection between ports x and y (between the
connectors to which the DUT is to be connected).
2. Click Thru/Line.
3. Click Port x-y Thru to execute a Thru/Line measurement.
4. Click Return.
Reflection
1. Click Reflect
2. Click Port x Reflect to execute a reflection calibration for test port x.
3. Click Port y Reflect to execute a reflection calibration for test port y.
4. Click Return.
