Cascade Microtech, offers a complete solution for multiport or differential linear devices and circuits to be characterized to 8.5 GHz. This turnkey solution includes dual high performance characterization probes, a series of dedicated dual ISSs (Impedance Standard Substrate), ENA Wafer Cal calibration software, an Agilent ENA Series RF network analyzer (E5071B) and Cascade's probing system. As part of this solution, Cascade introduces a series of dedicated dual and differential calibration standards as well as calibration software, ENA Wafer Cal. ENA Wafer Cal is a calibration software program that resides on the ENA instrument. ENA Wafer Cal provides productivity enhancements to ensure RF engineers, in addition to achieving both accurate and repeatable calibrations, can perform the whole procedure up to 10 times faster than using the front panel.
