A Package
A typical package is divided into two parts: The 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 package:
Example 1, A CITIfile
The “data” part
The “header” part CITIFILE
NAME MEMORY
MAG 3
DATA S RI
BEGIN
END
When stored in a disk 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 packages,
The Header
The header section contains information about the data that will follow. It may include
information about the setup of the instrument that measured the data. The header
shown in Example 1 has just the bare of information necessary; no instrument setup
information was included.
An
Array
of Data
An array is numeric data that is arranged with one data element per line. A CITIfile package
may contain more than one array of data. Arrays of data start after the BEGIN keyword, and
the END keyword will follow the last data element in an array.
A
package does not necessarily need to include data arrays; for instance, could
be
used to store the current state of an instrument. In that case the keywords DATA,
BEGIN, and END would not be required.
