The 2,200 magnets used in the CEBAF beam transport system have each undergone testing of their magnetic fields. Results of these measurements will be reported. {integral}Bdl profiles measurements (with a precision of {approx} 10{sup {minus}5}) for the 270 major solid-core dipoles used a multi-turn stretched wire with a reference magnet; the range of {integral}Bdl for a given (1, 2, or 3m) dipole family was {+-}5 {times} 10{sup {minus}4}. The {approximately} 700 quadrupole magnets` {integral}B{sub n}dl (1 {le} n {le} 16, R = R{sub pole}) values were measured with an accuracy of 0.01% of the quadrupole field component using a multi-turn Halbach bucked coil for 20% of the magnets and a reference magnet for all.
