Model 8020-47 DSP Digital Signal Processor | Discontinued

  • Model 8020-47 DSP Digital Signal Processor (this product has been discontinued).

The Model 8020-47 DSP Digital Signal Processor is designed to be used with GEOKON vibrating wire instruments for the elimination of spurious noise effected readings such as those caused by high voltage electrical cables and other forms of electrical interference. The digital signal processor removes the “errant” data by using proprietary techniques of digital filtering. It is ideal for unattended data acquisition systems where alarms may be triggered by preset threshold values. The DSP can also be directly interfaced with PCs to provide a stand-alone data acquisition system (contact GEOKON for details).

The Model 8020-47 has been replaced by the Campbell Scientific AVW200 Vibrating Wire Spectrum Analyzer Module.
