This makes them very useful for developers looking to produce ROM hacks or transitions, but are facing issues with compatibility and DRM.Īvailable for Windows computers, the No$SNS is 100% assembler code with relatively high accuracy compared to other No$ emulators. This VNA metrology application was originally developed for National Metrology Institutes and high-level industry laboratories but we do see now an increased interest from industry, accredited laboratories and academia. ![]() One of the reasons is to have access to a complete uncertainty budget and therefore being able to identify the main error sources (where to put the resources to increase the accuracy). ![]() The other reason is to compare the impact on accuracy by applying different calibration methods or calibration standard definitions on exactly the same S-parameter raw data. In addition it saves a lot of time for any accredited lab for the measurements and the needed quality management documentations. Just to come up with your best measurement capability calculations (needed for the scope of accreditation) allows you to save weeks of work compared to use the existing techniques. Other new implemented features are time domain conversion, material characterization calculations (complex permittivity and permeability) and mixed mode S-parameter conversions – all with linear uncertainty propagation. VNA Tools does support coaxial, waveguide and on-wafer S-parameter measurements. Even a virtual VNA is built in to create artificial measurements – this is very convenient for educational purposes as no VNA hardware is needed to demonstrate the S-parameter metrology and the impact from the different possible calibration methods.įrom Simon: I’m using also widely WinCal for another purpose : viewer of S-parameter files. Wincal from Cascade can be freely downloaded.
