Previous magnetic field measurements on the entrance half of the NIST undulator showed errors that resulted in a beam path deflection of 5.2 mm [Wallace {ital et} {ital al}., Nucl. Instrum. Methods A {bold 331}, 759 (1993)]. Pole height variations as much as .009{close_quote}{close_quote} gave rise to field errors of up to 2{percent} at a gap of 20 mm. We report on our effort to rebuild the NIST undulator through a series of {ital in}-{ital situ} and off-line measurements and modifications. Initial results indicate that at 40 A, a brightness of 2.5{times}10{sup 18} (ph/sec/mm{sup 2}/mrad{sup 2}/A/0.1{percent} BW) can be achieved. Commissioning of the undulator will take place in January 1996. {copyright} {ital 1996 American Institute of Physics.}
