The brightness of the radiation emitted by an ultrarelativistic e-beam passing through a magnetic undulator is sensitive to the beam quality (namely, energy spread and emittances) and to the undulator characteristics (i.e., possible random errors both in intensity and direction of magnetization, etc.). We analyse the spectrum distortion induced by the above effects and discuss the possibility of using the undulator radiation as a diagnostic tool. Finally, we also study the importance of near-field effects when the radiation is detected unfocussed off-axis and how they can combine with the effects induced by the beam emittances to produce a larger on-axis inhomogeneous broadening.
