However, there are some tricks that one can use to accomplish good results with the native software that are clunky and time-consuming. Since RFEx auto-adjusts RBW based on its span settings, exporting multiple consecutive sweeps of narrow span and combining the exported files with Excel into one large CSV is viable. The PITA factor can be mitigated with some skilled automating of the required steps via scripting and Excel VBA macros. FWIW, I did that in the past and ended up preferring Touchstone's quirks and cost, by far.
I bodged together a little Python script that will do basically the same thing by talking directly to the hardware (i.e. make sure no other software is talking to the RFEx; double-click on the script; wait for the command line program to finish; load the CSV file into WWB). It's not elegant, but it is pretty quick and painless and seems to get the job done.
Are the exported sweeps in Touchstone averaged at all?
