(between pins 1 and 2).
8. Adjust Parametric measurements
NOTE
If CAL 01, 02, and 03 were not performed, the
adjustments in this subsection should only be per-
formed if those constants that would have been set
in CAL 01, 02 and 03 are known to be correct.
" Limit" messages that appear during this calibration
are generally due to A or B Sweeps, A or B Gates,
or the measurement PAL, U975.
