Note 
S2P is a standard ASCII text file format that is used for scattering parameters from a 2‑Port measurement. This is a subset of SnP (where n equals the number of ports). An S2P file can be used as input for signal analysis.
The CSV and Text files contain setup information and final formatted data that are shown on the instrument display screen. This file information includes any post‑processing that was done on the data (smoothing, trace math, and so forth). These files contain the data for any traces that are displayed, including the memory traces. They also contain the markers that are turned on when the file is saved.
