2 Introduction
2.2.2 Decoders
Only digital velocity decoders are used in the PSV-500-3D. This enables very
precise and high-resolution acquisition of vibrations. With the H system the
decoder signals are directly transmitted digitally to the PC. With the M system
the signals are converted into analog signals and transmitted to the data
acquisition board of the PC.
The decoders are equipped with digital tracking filters which allow robust
measurements even if the optical signals are weak.
DV-04 With 14 measurement ranges, the DV-04 velocity decoder covers the
frequency range from 0 Hz to 2 MHz. This is the standard decoder of the
PSV-500-3D-M.
2.3 Setup and Properties
The decoder in the front-end as well as the data acquisition board determine
the metrological properties of the PSV. Depending on the application, there
are different models available. Their properties are summarized in the
following tables.
