Spectrum analyzer S4-77 is designed for visual observation and measurement of spectral components repetitive signals and stationary noise.
Technical characteristics of the instrument spectrum analyzers S4-77:
The range of frequencies of the device - from 20Hz to 600kGts;
The limits of acceptable error of measurement of the frequency of the input sine wave (in Hz) are equal to the values ​​calculated by the formula:
Δƒ = ± (10 -6 ƒ + Δƒ with n + Δƒ to +1 / τ acc)
