Measured the noise floor of the accelerometer to compare it with the seismic noise we measure with it (and the TFs i want to measure). Suspended it from the table using a very soft spring to make it quiet enough. Resonance frequency of suspension was ~1Hz (small peak visible in spectrum, damping of the thing took forever).
Seismic noise of the table is hitting the noise floor of the accelerometer at about 10Hz. Couldn't find the raw data from the seismometer measurements. Will update this later.
