Purpose of the development: For accurate measurement and registration of parameters of vibration measurement converters (VIM), measurement of amplitude-frequency characteristics of electronic units.

Recommended application field: In metrology, at the enterprises of Metrtestandart.

Technical characteristic: Measurement range of RMS voltage of alternating current, mV - from 3 to 8000 Limits of the permissible relative error at - ± 0.3 measurement of RMS voltage of AC,% - up to ± 0.5 Limits of the permissible relative error in measuring the conversion factor of the accelerometer by charge,% - ± 1 to ± 4 Limits of absolute error allowed for measuring the frequency response of filters A, B and C in accordance with GOST 17187-81, dB - ± 0.04 Limits of the permissible absolute error in the measurement of the response of octave and 1/3 octave filters in accordance with GOST 17168-82, dB - ± 0.04

The development stage readiness: Introduced in production

Description of the development:
()
The installation includes an AVKU-2 electronic unit, a vibration table, a standard VIP and a PC-compatible computer with the AVKU-XX software. The unit contains a sinusoidal generator based on a digital frequency synthesizer, a power amplifier (70 W) for controlling the shaker, two measuring channels with adjustable transmission factors, a controller with two ADCs (16 bits) and a USB interface for communicating with a computer, a power supply. The unit is controlled by the external computer via the USB interface. The frequency and amplitude of the output sinusoidal signal of the generator are programmed programmatically, the type of input amplifiers and the operating mode of the power amplifier are selected, the ADC mode (one or two channels, sample rate, length of samples) is set.
