SR785 Spectrum Analyzer

Some things to remember:

Use the appropriate coupling (usually AC coupling)
Use the appropriate input range
Use spectral units [V/rtHz] when making spectra
Don't make ground loops - set the ground to "floating"

Converting data files

The "display to disk" function creates .78D files, which may be converted to other formats using the SRT785.EXE utility, downloadable from the SRS website.

Note that the "/?" option by itself doesn't show you all of the options. For example, to see all of the ASCII output formats available, you have to do "/Oasc" with no other options.

My preferred format for transfer functions is: srt785 /D /Oasc /Cx,mag,p /Urms,lin,deg *.78D

The program:

SRT785.EXE

You can also set up the Print-Screen button to save an ASCII text file to disk.
