Understanding the CITIfile Data Format
CITIfile Keywords
CITIfile Keywords
Keyword Explanation and Examples
CITIFILE CITIFILE A.01.01 identifies the file as a CITIfile, and indicates the
revision level of the file. The CITIfile keyword and revision code must
precede any other keywords. The CITIfile keyword at the beginning of the
package assures the device reading the file that the data that follows is in
the CITIfile format. The revision number allows for future extensions of
the CITIfile standard. The revision code shown here following the CITIfile
keyword indicates that the machine writing this file is using the A.01.01
version of CITIfile as defined here. Any future extensions of CITIfile will
increment the revision code.
NAME NAME CAL_SET allows the current CITIfile "package" to be named. The
name of the package should be a single word with no embedded spaces. A
list of standard package names follows:
Label Definition.
RAW_DATA Uncorrected data.
DATA Data that has been error corrected.When only a single data array exists, it
should be named DATA.
FORMATTED Corrected and formatted data.
MEMORY Data trace stored for comparison purposes.
CAL_SET Coefficients used for error correction.
CAL_KIT Description of the standards used.
DELAY
_TABLE
Delay coefficients for calibration.
VAR VAR FREQ MAG 201 defines the name of the independent variable
(FREQ), the format of values in a VAR_LIST_BEGIN table (MAG, if used),
and the number of data points (201).Typical names for the independent
variable are FREQ (in Hz), TIME (in seconds), and POWER (in dBm). For
the VAR_LIST_BEGIN table, only the "MAG" format is supported at this
point. # #NA POWER1 1.0E1 allows variables specific to a particular type
of device to be defined. The pound sign (#) tells the device reading the file
that the following variable is for a particular device. The "NA" shown here
indicates that the information is for a Network Analyzer. This convention
allows new devices to be defined without fear of conflict with keywords for
previously defined devices. The device identifier (i.e. NA) may be any
number of characters.
