 ==== Limitations and What to Expect ====
-  - The first limitation is the size of your paging file and amount of RAM your system has.
-  - The FFT analysis library is limited to (2^31)-1 element double arrays. Note that Complex Samples are passed as an interleaved double array, the limitation for Complex FFTs is 2^30 I&Q samples.
   - Not all ACE plug-ins can support or have been updated to support large captures.
+  - The size of your paging file and amount of RAM your PC or Laptop has.
+  - Most Capture Controllers (e.g. ADS7-V2) take a snapshot to onboard RAM as the data rate is often too high to continuously transfer to the PC (reliably). For the SDP-H1 that's 64MB and the ADS7-V2 about 4GB.
+  - The FFT analysis library is limited to (2^31)-1 element double arrays. Note that Complex Samples are passed as an interleaved double array, the limitation for Complex FFTs is 2^30 I&Q samples.
   - Depending on the size of the Capture it could take a long time.
   - As the operation is memory intensive some applications may stop responding or your system may become unstable.
