Contour plot showing comb-gap pressure variation for the lateral Y-sense mode at 10000 Pa cavity pressure. The left hand inset plot shows 10 harmonic sweeps over a pressure range of 1000 Pa to 100000 Pa, simulated via the MATLAB interface in 30s. The vertical lines mark the 3 dB points from which the variation of bandwidth is plotted with pressure (right hand inset plot).
