Measurement model: each physical accelerometer supplies three channels: X, Y and Z. S0 is the measured reference acceleration; S1–S3 are response accelerometers. The displayed H1 quantity is an acceleration-reference transfer proxy, not a force-input FRF. A true force-based FRF requires a measured excitation force.
