Top panel: time series of the potential difference between the receiving electrodes during an interference test between SESAME-PP and CONSERT conducted in 2010. CONSERT operations clearly saturate the SESAME-PP receiving channels at 132 ms. Bottom panel: time series of the potential difference between the receiving electrodes during the descent of the Philae lander toward the comet. The saturation pattern is similar to that observed during the SESAME-PP/CONSERT interference test.
