cialog File Operations

The Data Folder

The cialog data folder is the name of a folder that is used to contain saved data. cialog will not create a data folder. It must be created outside of cialog. The cialog data folder is used to set the initial folder for the save, open, and export file operations.

The cialog data folder is specified with the Set Data Folder Dialog Box.

Saving Data Files

The File->Save Data menu command is used to save data. The standard system save dialog is used to acquire the specification of a file name. The initial folder displayed will be the cialog data folder. You can change folders using the dialog box, and save files at any part of the file system.

cialog data files have a .fcd (file of cialog data) suffix.

The contents of a data file are ASCII text, and can be examined with a text editor, if desired. Be careful, however, since a change in the file could cause the reloading of the data to fail. If you wish to analyze saved data with other programs, used the export command, which creates a very generic data file with a common format.

Opening Data Files

The File->Open Data menu command is used to open an existing cialog data file.

The file open mechanism is used to enter Multiple Data Set Mode. The only way to introduce a second set of data is by opening a saved data file. In other words, if you want to compare data, even from a single session, you must save some of the data in a file, so that it can be opened and graphed against captured data.

When a file is opened, the new data is added to any existing captured or opened data. If the graph is empty when a file is opened, then cialog will be in Single Data Set Mode. It will be possible to display all data which exists in the file. If the graph is not empty, then opening a file will put cialog into Multiple Data Set Mode. In that mode, the graph will show one category of data at a time, drawing the same trace from each data set. In order to stay in Single Data Set Mode when looking at a series of files, it is necessary to erase the graph between each open operation. The graph can be erased with the Graph->Erase Graph menu command.

Up to five files can be open at one time. When this limit is reached, the Open Data menu command will be disabled.

Exporting Data

The File->Export Data menu command creates a data file describing the most recently captured data. The command will not be enabled if there is no existing data graph constructed from captured data. The exported data file format follows either the csv (comma separated value) or tab delimited format. These two popular formats are readable by programs such as Microsoft Excel, or other spreadsheet and analysis programs. The format is determined by the file suffix that you supply on the exported file name, either .csv or .txt.

The exported data file contents consist of several header lines, followed by a table of data. There is one column of data for each value captured or computed by cialog. This ranges from a minimum of one column to a maximum of nine. A column header line will precede the table, and indicates the columns which are present, and their left to right order on the line. The column headings are:

Exported Data Column Headings
File Form Meaning
Freq. MHz Frequency of data sample
SWR SWR at CIA-HF
R Resistance at CIA-HF
X Reactance at CIA-HF
Z Impedance at CIA-HF
SWRL SWR at load
RL Resistance at load
XL Reactance at load
ZL Impedance at load
DB dB Loss on transmission line

Here is an example exported file in the comma separated value format.
