Schiaramento/annotazione:For verification of modulation meters on parameter FM. Ãåíåðà
torus of fm signal, generator of modulating voltages and generator the disc
ðåòíûõ frequencies consists of.
Descrizione del marchio dettagliata:To checked the parameters FM belong:
- measurement error of frequency deviation;
- harmonic coefficient of baseband signal in case of sinusoidal FM;
- frequency background and noise;
- transfer coefficient of frequency modulation in amplitude;
the directive can be used as a source of fm signal
with little harmonic coefficient of baseband signal in case of ñèíóñîèäàëü-
the FM Noy, with low level of frequency noises and accompanying AM, as a
low-noise frequency multiplier.
the reference measuring equipment widely applies to ðàçðàáîò-
SIF, production, operation and deviometers repair; provides them
regular certification; guarantees the measurement authenticity when solving
complicated engineering and metrological tasks.
