Maximum Size of Binary Merge File
When digitizing and spooling a "Binary Merge" file to disk
(i.e. all channels in one binary file, 4 bytes per point), the
maximum file size is limited by the amount of free space on your hard disk.
For example, you could digitize 10 channels at 1ks/sec/ch for 30 days and create a 103GB file,
provided you had 103GB free.
This requires iNet32.dll
≥ v18.104.22.168. Older versions were limited to a 2GB maximum binary merge file size.
The maximum number-of-scans is 2 billion (2e9).
Maximum Points for entire digitization
You can digitize virtually forever provided you do not overload your RAM or hard disk space.
For example, you could digitize 100Ks/sec for 100 years with Points-Per-Scan
set to 10e6 (40MB Ram buffer per channel) and Number-of-Scans set to 31e6.
