The CSC- I will perform all of the 'classical' shock tests as defined in MIL-STD-810 and is equally useful for environmental qual testing or production test screening. Automatic calculation of pre- and post-pulse compensation assures the maximum performance from your test system. Test setups are done in a setup screen using English or Metric units and results are plotted in a plot screen. It is available on a dual-function Random / Classical Shock Control Card. The software generates the required pulse, and the waveform generator drives the shaker system to produce the desired shock pulse.
