ASCII Data Formats

CITIFile (Common Instrumentation Transfer and Interchange flle) is an ASCII data format that is useful when exchanging data between different computers and instruments. CITIhles are always saved when the ASCII format has been selected as shown below:

	.,. :)	~...........:.:. ..:.:.:<.:.:.. / :..	,. :.:.,/. i i	. . . . . ;
If ~~~~~~~~..“~~or ,~~~~~~~~~~,,					or ;~~~~~..;,~~~~~:~~ is s&y&d, a CIl’Jae is saved for

each displayed channel with the sufhx letter “D”, or “F”, followed by a number. The number

_ _ _

following “D” and “F” llles is the channel number. When ~~~~~:~~:~~~~~~.......>>>.s.....::...^...............,,.,.,.,.,.,.,.,.,.,.,.,.,.. is selected, an 91”

file is saved for channel l/channel 3, and an “r5” ille is saved for channel 2Mannel4. For more information on the CITIFiIe data format as well as a list of CITIFile keywords, refer to Appendix A, “The CITIFile Data Format and Keyword Reference.”

S2P Data Format

This format creates component data files that describe frequency dependent linear network parameters for 2 port components These hles are assigned a hlename with the sulhx “S” and are only outputted (that is, they cannot be read in by the analyzers).

Up to two S2P files are saved: Sl for channel 1, and S2 for channel 2. S2P files 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 hle is only outputted when the ail of following conditions are met:

na full two-port or TRL two-port correction is turned on
