Meter modulation and frequency deviation & nbsp; SK3-45 & nbsp; for rapid and precise measurement of the modulation signal parameters sayaznoy and instrumentation. Can also be used as a precision demodulator signal and noise parameters measuring signal sources.

Having built the microcomputer allows to increase productivity in the measurements and to extend the functions of the device before being able SK3-45 system providing measurement of coefficient AM, frequency deviation voltage and an input signal frequency and harmonics of the frequency factor of the modulating signal.

Calculation results of measurement and correction is performed digitally. The device is provided SK3-45 logarithmic count of measured values.

For operative automatic calibration modulation meter has a built exemplary source signal.
