A description of the technique used for performing a variety of SQUID NMR measurements in fields varying from 3.7 to 309 G is presented. Pulsed NMR, cw NMR, adiabatic fast passage, and static susceptibility measurements have been made on liquid /sup 3/He, using the same detection system, in the temperature range 1.2K--2mK. The spin-lattice relaxation times varied from 100 s at 1 K to as fast as 0.26 ms at 2 mK. The spin--spin relaxation times varied from 3 x 10/sup -5/ s in 309 G to nearly 3 x 10/sup -3/ s in 3.7 G.
