a, Experimental pumped current at constant amplitude with a driving frequency of 30, 60, 80, 160 MHz as blue, red, yellow and purple dots, respectively. Black lines are calculations made with a Markovian equation, the dashed lines designate the ideal pumped current I = ef. b, Differential conductance obtained by numerical differentiation of panel (a) data. Black lines are numerical derivatives of calculations of panel (a). Lower operation frequencies give sharper pumped current and conductance.
