Commands on the menu bar at the top of the screen:
FILE:
Load --
Load a raw data file from a previous scan. After this file is
loaded, its data is just like the original scan. The cursor can be
used to read out the numeric values.
When a data file is being displayed, the name of the file appears
at the top of the graph.
Save --
Save the raw data for the last scan that was done. If you clicked
the RESCAN button, the data that will be saved is for the last
scan. Even though the earlier scan is being displayed on the
graph, its raw data was replaced in memory by the new data
corresponding to last rescan command. The raw data is saved in a
file with the extension .scn. Another file is created with the same
name and the extension .scx. The .scx file has data in a format
that can be read into a spreadsheet. The format of this file is
shown in Appendix 5.
Print -- Print the graph on the system printer.
Load Calibration --
Load a calibration data file for a particular test setup or adapter.
These files have the .acal extension.
Load Config --
One of several configuration files can be loaded. A selection
window will show all the files in this folder with the .cfg
extension.
Quit --
Stop the program and exit.
This is the same as the QUIT button at the bottom of the screen.
FUNCTIONS:
Measure Cable --
This command is used to measure several parameters related to
the transmission line. A message box pops up to prompt that the
cable should be either open or shorted at the far end for these
tests to be valid. After this is ready, click OK to continue.
Other dialog boxes prompt for the velocity factor and the length
of the cable, if known. If the length is entered as Zero, the length
will be determined using the velocity factor that was entered. If
the length is non-zero, the length is assumed to be accurate and
the velocity factor will be determined.
