What is TRL calibration?

re:What is TRL calibration? 
Traditional, full, two-port calibration methods typically use three impedance standards and one transmission standard to calibrate a vector network analyzer (VNA). The standards normally used in this method are shorts, opens, loads, and thrus (making this what is often referred to as a SOLT calibration). A thru-reflect-line (TRL) two-port calibration kit uses at least three standards to define the calibrated reference plane. The measured parameters of the thru, reflect, and line standards in a TRL calibration kit perform the same function as a SOLT calibration.

re:What is TRL calibration? 
A variation of the TRL method is the line-reflect-line (LRL) calibration, wherein one line section represents the thru portion of the calibration. LRL kits are typically used in coaxial applications where frequency bandwidth and mechanical limitations may prohibit the use of a single line section.

What are the disadvantages of TRL calibration?

re:What is TRL calibration? 
Some disadvantages of the TRL calibration are; a) this method can only be used to perform two-port calibrations, and b) the length of the air lines may prohibit performance of a TRL calibration at low frequencies. (Maury Microwave's TRL / LRL coaxial tri-kits are designed to overcome these disadvantages by including precision fixed loads, which can be used to perform one-port calibrations and calibrations at low frequencies.)

Re: What is TRL calibration? 
It will be true that Industry compliance standards will obviously be the primary factor taken into consideration along with guidelines established by the manufacturer of the instrument.

Re: What is TRL calibration? 
TRL calibration is excessively correct, in many cases more correct than an SOLT cal. But some of calibration kits includes TRL standards. TRL Cal is most done comply when you needed a high level of certainty and do not have calibration standards in the same connector type as your DUT
