Internal Measurement Arrays

Internal Measurement Arrays
The following sections describe the sequence of math operations and the
resulting data arrays as the measurement information flows from the
raw data arrays to the display. This information explains the
measurement arrays accessible via GPIB.
Figure 6-3 is a data processing flow diagram that represents the flow of
numerical data. The data passes through several math operations,
denoted in the figure by single-line boxes. Most of these operations can
be selected and controlled with the front panel CONFIGURE block
menus. The data is stored in arrays along the way, denoted by
double-line boxes. These arrays are places in the flow path where data is
accessible via GPIB. While only a single flow path is shown, two identical
paths are available, corresponding to measurement channels 1 and 2.

Raw Data Arrays

These arrays are linear measurements of the inputs used in the selected
measurement. Note that these are pairs of complex numbers. The arrays
are directly accessible via GPIB and are referenced as CH[1|2]AFWD,
