Specifies the calibration method.

You do not need to use a selector string to configure or read this property for the default signal instance. Refer to the Selector Strings topic for information about the string syntax for named signals.

The default value is SOL.

SOL 0

Full 1-port calibration using atleast three distinct reflection standards, typically named Short, Open and Load.
SOLT 1

Full 2-port calibration by performing two SOL calibrations on the two ports using atleast three distinct reflection standards, and a Thru cal using a transmission standard connecting the two ports. Use Thru Method property to select a suitable Thru cal procedure.
TRL 2

Full 2-port calibration using a Thru, at least one Line, and one Reflect standard (Thru-Reflect-Line). The Thru standard can be an flush Thru or can have non-zero length (LRL, Line-Reflect-Line). The Reflect standard has to be identical for both ports. If multiple lines with different lengths are defined, the measurement automatically splits the measurement frequency range into segments and picks the line standard with appropriate length for each segment. The reference impedance of the calibration is the characteristic impedance of the Line(s).
