Abstract: An assessment on the capabilities of modern spectropolarimeters andmagnetographs is in order since most of our astrophysical results rely upon theaccuracy of the instrumentation and on the sensitivity of the observables tovariations of the sought physical parameters. A contribution to such anassessment will be presented in this talk where emphasis will be made on theuse of the so-called response functions to gauge the probing capabilities ofspectral lines and on an analytical approach to estimate the uncertainties inthe results in terms of instrumental effects. The Imaging MagnetographeXperiment IMaX and the Polarimetric and Helioseismic Imager PHI will beused as study cases.
