| dc.description.abstract | High precision in hydroacoustic instruments for fisheries research demands high precision and
reliability in the test instruments. To simplify the test measurements, a special test unit has been
developed. The operating principles are described, and a technical description is given for this
special-purpose signal generator. Application of the unit is described in detail, and an easy way to
verify the accuracy of signal amplitude and frequency is recommended. Finally a computational
example to derive correction factors is given. | en |
