As can be seen in Fig. 1, the 0.4cc coupler does not produce the very sharp resonance at about
12 kHz typical of the 2cc coupler (dotted line). The 0.4cc coupler’s high frequency behavior
is much more linear and does therefore not degrade the reproducibility of high frequency
measurements.
A typical receiver response is shown in Fig. 2.
