Yes just to clarify my post it should read "capture" and the force of the step will be regictered by a load cell to then be recorded by the SCADAS III transient response. Can anyone see that this will not work for some reason? Another conceren is to have the range low enough on the PQCA charge input card. the signal will come from a rotary type load cell.
Any of the LMS Test.Lab acquisition modules that support time recording (measuring throughput) could be used to measure a transient - so yes, LMS Test.Lab Transient Capture could be used or also Signature Testing or Spectral Testing with the Time Recording add-in and Throughput turned on. Within the Durability products, Time Data Acquisition could be used.
As with any measurement, you need to match the measured value to the transducer and the input card. The PQCA has the following input ranges. If this is not sufficient to measure the low force levels with your transducer you would need a transducer with different sensitivity.
