Measurer SK3-43 (SK343,SK3 43, ck3-43, ck343, ck3 43)
Carrier frequency range: 0,15-500 MHz (AM) 4-1000 MHz (FM).
Modulating frequency range: 0.03-60kHz.
Sensitivity: 50 mV (0.15-4 MHz and 250-500MHz), 30 mV (4-250MHz), 300mV (500-1000MHz).
Measuring range: Frequency deviation 1-500kHz, AM factor 1-100%.
Built-electron-counting frequency meter, mix on low bandwidth, input preselection.

Measurer SK3-43 modulation is designed for precision measurement of AM signals of different transmission equipment and test oscillators.
The presence of digital readout of the measured values, indicating a continuous adjustment to the frequency of the input signal and its level, frequency-locked loop oscillator and oscillator frequency setting the built-in frequency counter considerably reduces the measurement time.
Thanks to the automatic stabilization of a wide dynamic range, low distortion introduced by the transportation mechanism measurer SK3-43 in the measured signal with the demodulation is possible to accurately analyze the envelope of the signal from external devices - spectrum analyzers, ISI, oscilloscope connected to the woofer output.
The presence of the instrument measurer SK3-43 switchable low-frequency band tract allows you to analyze the signal at the optimal signal / noise ratio.
Preselection mode output provides a measurement input deadbeat coefficient AM in the presence of harmonics of the carrier frequency.
