Modulation meter '' SK3-46 ''.
Instruments for adjusting and controlling the PTA.The modulation meter "SK3-46" was produced presumably since 1987. Designed to measure the frequency deviation of FM signals and the coefficient of AM signals. The instrument can also measure the AM coefficient accompanying the FM signal and the frequency deviation accompanying the AM signal. The presence of a low frequency output and a low level of harmonics introduced into the measured signal allows using the device to measure the distortions of the modulation law of AM and FM signals. The frequency range of the input signal is 10 ... 1500 MHz. Overall dimensions 260x93x375 mm. Weight 3.3 kg. A detailed description of the device is available on the Internet.
