I wouldn't go as far as stating that the files are not PC compatible.
Of course, you'll probably need some special hardware that does the A/D
and D/A conversion, respectively, but i'm pretty sure most of what the
R&S SMBV100 does apart from data conversion is just software running on
an embedded PC. Plain x86 type hardware, for that matter, as it's
running either MS Windows or Linux (can't tell directly from the R&S
website picture, but the more recent the hardware, the higher the
probability of Linux instead of Windows for R&S stuff)...
 
It still is very much $$$ though :-(
