Performance

Devices under test (DUTs) of up to 23 kg (50 lbs) can be driven to acceleration levels typical of those found in seismic specifications. Performance envelopes of the APS 129 shaker with the PA 500 DM power amplifier are given in the diagram below. These envelopes represent the maximum acceleration with bare table (no payload mounted) that can be achieved on the table.
