Fig. 3 - Horizontal direction impulse response. Scope was connected to both channels output, with same polarity. (for mono signal) At about 3.9 div/cycle the horiz fn = 4.4 Hz. This fig is with the SME horiz damper engaged to about max level with the fluid. Clearly the impulse is being damped out at a generally greater rate than in Fig. 2 but is also clearly less than critically damped, given multiple cycle settling time.
