Definition of CITIfile Terms
This section will define the following terms:
• package
• header
• data array
• keyword
A CITIfile Package
A typical package is divided into two parts: The first part, the header, is made up of
keywords and setup information. The second part, the data, usually consists of one or more
arrays of data. Example 1 shows the basic structure of a CITIfile package:
Example 1, A CITIfile Package
The "header" part CITIFILE A.01.00
NAME MEMORY
VAR FREQ MAG 3
DATA S RI
The "data" part BEGIN
-3.54545E-2, -1.38601E-3
0.23491E-3, -1.39883QE-3
2.00382E-3, -1.40022E-3
END
When stored in a disk file there may be more than one CITIfile package. With the 8510
network analyzer, for example, storing a "memory all" will save all eight of the memories
held in the instrument. This results in a single file which contains eight CITIfile packages.
