The purpose of the present paper is to propose two scenarios for measuring high frequency noise. The first one uses inductive coupling to an LC circuit, and describes the measurement of noise cross-correlations as in an Hanbury-Brown and Twiss geometry. The second one uses the photo-assisted transfer of two electrons in a normal metal--superconductor circuit, which is capacitively coupled to the mesoscopic circuit to be measured.
