Abstract: Tests of a LDA system reveal a biasing influence of the low burst density limit, of the phase noise, and of the noise modes of LDA ope-ration. The biasing effects are illustrated on velocity histograms and on power spectra. Conditions for reliable histograms and turbulence power spec-tra acquisition are discussed.
