Ascii Data Formats; Citifile; S2P Data Format - Agilent Technologies 8719D User Manual

CITIFile (Common Instrumentation Transfer and Interchange file) is an ASCII data format that
is useful when exchanging data between different computers and instruments. CITMles are
always saved when the ASCII format has been selected as shown below:
each displayed channel with the suffix letter "D", or "F", followed by a number. The number
more information on the CITIFile data format as well as a list of CITIFile keywords, refer to
Appendix A, "The CITIFile Data Format and Keyword Reference."
This format creates component data flies that describe frequency dependent linear network
parameters for 2 port components. These files are assigned a filename with the suiiix "S" and
are only outputted (that is, they cannot be read in by the analyzers).
Up to two S2P iIles are saved: Sl for channel 1, and S2 for channel 2. S2P illes are not stored
for channel 3 or channel 4 because the data would be redundant. Each S2P file contains alI
four S-parameter data.
An S2P file is only outputted when the all of following conditions are met:
a full two-port or TRL two-port correction is turned on
n
Error-corrected data CITI files are always saved along with S2P files.
