Spectrum analyzer SK4-83
|
SK4-83 spectrum analyzer for measuring the absolute and relative levels of the spectral components of the continuous and periodic signals periodically recurring pulses, as well as for the purpose of the spectral density of the stationary noise signal.
spectrum analyzer SK4-83 provides supervision and continuous measurement of the spectrum of periodic oscillations of complex shape (AM, FM, PM); determining a modulation spectrum distortion; and by measuring spurious spectral components, occupied bandwidth and out of band spectra of discrete levels and frequency spectra of amplitude and frequency intervals between them, nonlinear distortion by the level of two-harmonic and third-order intermodulation distortion; panoramic observation and measurement of the gain of two-frequency range. The internal microprocessor controls the operation modes, the measurements and calculations, performs correction of measurement errors, diagnosis units and devices in general. Control device SK4-83 by entering commands through a front panel or CPC. Modes devices and processed measurement results are displayed on alphanumeric display and are issued in a FRC. Span: 0-1 MHz bandwidth at -3 dB of 3.16 Hz-31.6 kHz (discretely through 1; 3,16; 10) <.. / p> limits of basic measurement errors: Dynamic range: maximum input signal level: 10 (without an external attenuator).
