Internal Measurement Arrays
CH[1|2]BFWD
and
CH[1|2]RFWD
. Raw data for AUX INPUT is not
available via GPIB. Use the corrected data array to access AUX INPUT
data.

Raw Data Arrays
Ratio Calculations
These are performed if the selected measurement is a ratio (e.g. A/R or
B/R). This is simply a complex divide operation. If the selected
measurement is absolute (e.g. A or B), no operation is performed.
Error Correction
Error correction is performed next if correction is turned on. Error
correction removes repeatable systematic errors (stored in the error
coefficient arrays) from the raw arrays. The operations performed
depend on the selected measurement type.
