Cascade Microtech announced the release of WinCal 2006 software to address the testing challenges brought on by the increase in the volume of complex, high-speed semiconductors that are designed and tested for use in mobile communications products such as mobile phones, PDAs and laptop computers.

Since the responsibility for testing often falls to the research and development team, many engineers must perform high-frequency device characterization using a wafer probing station coupled with a vector network analyzer (VNA). WinCal 2006 software is designed to offer fast start for new and experienced users, high confidence in RF measurements, and support for multiport calibration on differential devices.

WinCal 2006 automates calibration of the VNA with ISS (impedance standard substrate) standards at the probe tip to remove repeatable errors from the VNA, cable and probe losses and reflections. To enable a fast start for system users, WinCal 2006 provides guidance systems including wizards and video tutorials, auto selection of compatible standards based on system set-up, automatic tracking of physical elements of the system, ISS management and visual map of ISS.

Automated calibration techniques include SOLT (short, open, load, thru), LRM (line, reflect, match), and LRRM (line, reflect, reflect, match). The LRRM and LRM/LRRM load inductance corrections provide accuracy improvements over the basic LRM method.

With enhanced ISS mapping and test system validation, WinCal 2006 steps through the calibration sites logically to ensure that no sites are missed during the calibration process. WinCal 2006 assures repeatable results through its system validation and drift monitoring capability on all four ports of the device simultaneously.

The software is designed to solve a wide variety of common problems including data correlation, training of new users, obtaining correct calibration coefficient definitions, calibration verification, erroneous use of untrimmed or non-50 ohm loads, and determining the source of unexpected or suspect measurement data.

The WinCal 2006 software starts at $5,000 for a single license. Delivery is three weeks upon receipt of order.
