The latest version of the WinCal XE measurement software from Cascade Microtech is written to increase the accuracy of on-wafer RF measurements. The new software version includes hybrid calibrations for multiport measurements, handling as many as four ports; local data manipulation for measurement validation and data analysis; and a host of new device characterization tools. The straightforward software supports a wide range of calibration schemes, including eLRRM, SOLT-eLRRM, SOLT-SOLR, and multiline TRL for comparison to NIST-style reference calibration.
