Keyword

Explanation and Examples

CITIFILE

CITIFILE A. 01.01 identifies the Ele as a CITIflle, and indicates the

 

revision level of the llle. The CITIflle keyword and revision code must

 

precede any other keywords. The CITIlile keyword at the beginning

 

of the package assures the device reading the file that the data that

 

follows is in the CITIllle format. The revision number allows for future

 

extensions of the CITIflle standard. The revision code shown here

 

following the CITIflle keyword indicates that the machine writing this

 

file is using the A.O1.O1 version of CITIille as dellned here. Any future

 

extensions of CITIflle will increment the revision code.

NAME

NAME CAL-SET allows the current CITIllle “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 VARLIST~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 VARLIST-BEGIN table, only the “MAG” format is

 

supported at this point.

 

#NA POWER1 1 .OEl 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 deilned devices The device

 

identiiler (i.e. NA) may be any number of characters.

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

 

VARLIST~BEGIN construct is used. CITIfiIe revision A.0140 supports

 

only the SEG (linear segment) segment type.

SEG-LIST-END

SEG,LIST-END defines the end of a list of independent variable

 

segments.
