Exact Uncertainty Calculator
This software can be used to calculate and plot Transmission and Reflection, Magnitude and Phase, measurement uncertainty, for VectorStar and Lightning family VNAs. It takes into consideration different calibration methods and kits, different conditions such as IF BW, and non-zero s11, s22, and s21, s12 conditions for transmission and reflection uncertainties respectively.
WindowsGPIB (version 3.79)
WindowsGPIB is a Windows®-based program that sends and receives program data over GPIB, in response to commands entered from the keyboard or from a command file, similar but friendlier than NI's WIBIC. It is a good tool for testing mnemonics and commands while developing ATE programs. Windows GPIB supports only NI GPIB.
Noise Figure Uncertainty Calculator (version 1.0.1)
The VectorStar Noise Figure Uncertainty Calculator is a standalone program used to provide the user a tool for easily determining measurement uncertainty while using the VectorStar VNA Option 041 – Noise Figure. The calculator can be installed on the VectorStar instrument desktop or on a Windows XP/Windows 7 PC.
CapVNA (version 1.0.1)
CapVNA is a Windows program to capture, display, save and print the graphical and textual data from VectorStar VNAs. The displayed data can be loaded from a flash drive where it was previously saved at the VNA or captured directly from the VNA over the GPIB port. The displayed data can be saved in a variety of formats to the PC's internal disk drive or a network drive and printed to a local or network printer (including color).
Cal Kit File Maker
The Cal Kit File Maker program provides all the files necessary to create a calibration kit file for the VectorStar, Lightning and ShockLine VNAs. The program provides a convenient set of menus for entering the required information for the different standards in the calibration kit. The program does not perform calculations; it takes the input provided and creates files in the appropriate format.
