The effect of random magnetic field errors are introduced into the calculations of spectral characteristics of tunable undulators for the proposed 7 GeV Advanced Photon Source (APS). Single electron calculations are made for an undulator with a first harmonic radiation tunable between 3.5 and 13 keV. Using the universal curves developed by Kincaid, the effect of randomly distributed field errors on the first and third harmonics of two proposed typical undulators are calculated. It is found that the lower limit of 0.5% in field errors is more than sufficient for the successful operation of the undulators planned for the APS.
