Automating Measurements
Saving Measurement Results
Saving
the
Measurement
to
Disk-Save
ASCII
The analyzer has a Save
ASCIf
feature which saves the measurement
trace in a format compatible with many popular spreadsheet programs
such as Lotus@
l-2-3@
and Microsoft Excel@. The measurement can also
be saved in lbuchstone format for importing data into CAE programs. The
measurement is saved to a
file
on the analyzer’s disk.
The following program segment shows how to save the measurement in Lotus
l-2-3
format to a file on the analyzer’s non-volatile RAM disk, and then how
to transfer that file into your program and store it as a file on your computer
disk.

With the Save ASCII feature, you can read the measurements into your
CAE or spreadsheet program, and perform statistical analysis on the data,
such as mean and standard deviation on groups of
DU’&.
For information on transferring disk files between the analyzer and your
computer, refer to the “Example Programs” chapter of the Programmer’s
Guide.
