The FANTASIO+ set-up, \textit{Mol. Phys.} 2010, \textbf{108}, 2158-2164} (for 'Fourier trANsform, Tunable, diode and quadrupole mAss spectrometers interfaced to a Supersonic expansIOn') was upgraded by implementing a pulsed nozzle and a liquid injector. Experiments were performed to test the new capacities of this improved set-up. The first results will be presented, among which the CW-cavity ring down spectra of the $\mathrm{<mrow\; data-mjx-texclass="ORD">12</mrow>}$C$2$H$2$-H$2$O and $\mathrm{<mrow\; data-mjx-texclass="ORD">12</mrow>}$C$2$H$2$-D$2$O absorption bands in the 2CH excitation range (1.5 $\mu$m). The first analyses of these spectra will be presented.\
