Supported File Types

SR785 Dynamic Signal Analyzer
Supported External File Types
Four different file types are currently supported by the SR780 file conversion utilities.
ASCII Files
ASCII files consist of plain ASCII text. ASCII files written by the SR780 file conversion
utilities consist of an alphanumeric header with instrument setup information followed by
a number of columns of data values. Columns are separated by 'TAB' characters and
each line is terminated with a carriage-return line-feed pair. For input, the conversion
utilities expect values to be separated by any whitespace character with no leading header
data. Characters after the last expected data value are ignored.
SDF Files
Standard Data Format, or SDF, is a file format supported by Hewlett-Packard instruments
and is designed to allow data sharing among various analyzers. The SR780 file
conversion utilities include a program (SDFTOSR.EXE) to translate version 3.0 SDF
files to SRS trace (.78D) files. Note that because of specific differences between HP
analyzers and the SR780 it is impossible to exactly match instrument setups on the two
analyzers, however, measurement data is transferred exactly.
Matlab
MAT-Files
MATLAB
is a popular program for doing mathematics and for the analysis of numeric
data. Although it easy to import ASCII data directly into MATLAB
, it is faster and more
efficient to use the binary MAT-File format. The conversion utilities include the
capability of directly converting a SR780 display file into a binary MAT-File.
Universal File Format
The Universal File Format is a specification for an ASCII database capable of describing
the geometry, degree-of-freedom, and measurement data used in structural analysis. Most
modal analysis programs are capable of importing measurement data formatted in
Universal File Format. The SR780 file conversion utilities include the capability of
converting SR780 display files into Universal File Type 58 (Function at Nodal DOF) data
sets.
