Example of defining the TRL calibration kit
You need to enter the definition of the TRL calibration kit to perform TRL
calibration.Follow these steps to define the following calibration kit given as an example.
• THRU (Delay 0 ps, Offset Loss 1.3 Gohm/s)
• REFLECT(SHORT, Delay 0 ps)
• MATCH (@0 to 2GHz)
• LINE1 (50-ohm transmission line, Delay 54.0 ps @ 2G to 7GHz)
• LINE2 (50-ohm transmission line, Delay 13.0 ps @ 7G to 32GHz)
