DataViewer
Windows graphics program for viewing SR785 files. Graphs
can be pasted to the clipboard or saved in PCX, BMP or GIF
format. You can perform simple editing, add pointers and text,
change scaling, perform simple math operations, and copy
measurement data into other applications.
Data Conversion Utility
Data, waterfall and capture files can be converted to ASCII.
Data files can also be converted to Universal File Format,
SDF format or MATLAB MAT-File Format. SDF and SR780
files can be converted to SR785 format.
Time Capture
Captures time data for later analysis (FFT or Octave). Up to
2 Msamples (8 Msamples optional) of data can be saved.
