Understanding the CITIfile Data Format
CITIfile Keywords
SEG_LIST
_BEGIN SEG_LIST_BEGIN indicates that a list of segments for the independent
variable follow. Format for the segments is: [segment type] [start] [stop]
[number of points]. The current implementation only supports a single
segment. If there is more than one segment, the VAR_LIST_BEGIN
construct is used. CITIfile revision A.01.00 supports only the SEG (linear
segment) segment type.
SEG_LIST
_END SEG_LIST_END defines the end of a list of independent variable
segments.
VAR_LIST
_BEGIN VAR_LIST_BEGIN indicates that a list of the values for the independent
variable (declared in the VAR statement) follow. Only the MAG format is
supported in revision A.01.00.
VAR_LIST
_END VAR_LIST_END defines the end of a list of values for the independent
variable.
DATA DATA S[1,1] RI defines the name of an array of data that will be read later
in the current CITIfile package, and the format that the data will be in.
Multiple arrays of data are supported by using standard array indexing.
Versions A.01.00 and A.01.01 of CITIfile only support the RI (real and
imaginary) format, and a maximum of two array indexes. Commonly used
array names include the following: "S" for "S parameter" Example: S[2,1]
"E" for "Error term" Example: E[1] "USER" for "User parameter" Example:
USER[1] "VOLTAGE" Example: VOLTAGE[1] "VOLTAGE_RATIO" for a
ratio of Example: VOLTAGE_RATIO[1,0] two voltages (A/R).
