*
By averaging readings noise can be reduced to less than one least significant bit (Isb).
**
These figures are based on an HP 98640A whose data were processed and controlled
by routines from the HP 98645A Measurement Library. The accuracy figures show
the worst case affects of noise after the library's noise reduction routine is used.
