Pico Technology also offers two short, open, load, and thru (SOLT), 4-piece, 5-port calibration kits in both male and female genders. All kits have high-performance tight-tolerance stainless steel interface connectors. Kits are supplied as an assembled five-port "Y" SOLT, either male or female. They can be disassembled for individual usage, or for economical refurbishment should a calibration standard be damaged.

Each SOLT is supplied with traceable calibration data linked to the kit serial number and is supplied in a protective carry case. Both the Standard and Premium kits offer exceptional residual directivity at their price points. It is this that combines with a good un-corrected port match on the PicoVNA 106 to deliver exceptional price-performance. Premium kits are calibrated to reduced uncertainty using TRL Thru Reflect Line inter-comparison above 1.5 GHz.
