Touchstone format

A file format for storing S-parameters, the file format for circuit simulation software from EEsof (currently a division of Keysight) has become the de facto standard.
The numbers between s4p, s8p, s16p and extensions change depending on the number of terminals (input/output ports). s4p is the most common and corresponds to a differential input/output statement = 4-terminal circuit (4-port network analyzer).
S-parameter measurements and submission in Touchstone format are available for many of our main connectors, especially for high frequencies. Please contact us from our website or consult with the sales representative in charge of your company.
