In some cases field-cycling experiments requires both a good defintion of the Larmorfrequency withing the ULF regime (ultra low frequency) and high magnetic fieldhomogeneity during signal acquisition. In addition, sharp pronounced transients whenswitching the magnetic field may produce undesirable effects in the experiments.Depending on the available hardware, such limitations can be overcomend more or lesseasily with specific solutions. In any case, the availability of an specific tool for theanalysis and diagnosis of these limitations or any other due to system failures isappreciated. We will discuss a technological integrated universal platform that can beadapted to any magnet-geometry. The system compensates external static and timedependentmean fields and first order gradients, correct magnetic field inhomogeneityand allows to scan and analyze the time and spatial dependence of the magnetic field.6th conference on Field Cycling NMR relaxometry - Turin, Italy 4-6 June 2009P 17
