Accessing Other Measurement Arrays
The preceding sections describe how to query the formatted data array
using the TRACE:DATA? query with the argument CH1FDATA. The
formatted array is the last array in the analyzer's data processing chain,
and is generally of most interest.
The analyzer also allows you to query other measurement arrays which
are earlier in its data processing chain. Figure 6-2 shows the data
processing chain.

The first array is the Raw Data Array, which contains each of the
separate input components (A, B, R, B*, R*, X, Y, AUX) immediately
after they are measured. These arrays can be queried and set, but doing
so is of limited use, since the data values contained in the arrays are
uncorrected, and are not directly correlated to any meaningful reference,
such as 0 dBm.
