Digital Velocity Decoder D-VD-0N Ultrafast FPGA-based Digital Signal Processing Optomet Vibrometers feature an end-to-end FPGA-based digital signal processing allowing a fully digital read-out of the measurement data. Digital signal processing avoids any drawbacks of analog demodulation which may result from component aging, temperature dependencies, noise and non-linearities. Significantly higher sensitivity, better resolution, and stability are the benefits of OptoMET’s end-to-end digital signal processing. Extremely low noise levels produce precise results even from poorly reflecting measurement objects. HIGHLIGHTS: • Digital decoder • 7 velocity measuring ranges • Frequency range: 0 Hz - 100 kHz • Max. velocity up to 2.5 m/s • Resolution down to 12 nm s-1/√Hz • Max. linearity error: 0.5 % Start Velocity Decoder All vibrometers series feature by default a velocity decoder and can be supplemented with a suitable displacement and/or acceleration decoder. The D-VD-0N velocity decoder is the versatile solution for various types of non-contact vibration metrology tasks. With its 8 velocity measuring ranges, it can measure up to 100 kHz and thus well above the audible acoustic range. Digital signal processing provides excellent linearity and measur
