Using Binary Data Encoding
The analyzer stores its internal data with approximately 5 significant
digits of resolution. Using REAL,32 or ASCII,5 format provides sufficient
precision for data transfers
. However
, REAL,64 may be necessary when
using a programming language which does not support IEEE 32-bit
floating point.
