Pulse voltage voltmeter '' B4-24 / 1 ''.
Instruments for adjusting and controlling the PTA.The voltmeter of impulse voltage "B4-24 / 1" has been produced by the Minsk plant "Kalibr" since 1989. The voltmeter is designed to measure the amplitude and instantaneous voltages of repetitive and single-shot signals of pulse and pulse-modulated form, as well as alternating signals of both harmonic and highly distorted form with simultaneous measurement of amplitude and time parameters, DC voltages of both polarities. A distinctive feature of the device is a wide 700 MHz bandwidth with high accuracy (0.5% error) and measurement speed up to 105 measurements / s. The device can be used as a high-speed analog-to-digital converter and signal sampler, and when using an external display, it can also be used as a broadband stroboscopic digital oscilloscope with the ability to accurately measure the amplitude and time parameters of the signal. A wide dynamic range of voltage measurement (from 1 mV to 1000 V) is provided by the stroboscopic probe with 1:10 dividers - nozzles attached to the device; 1: 100 and external scale amplifier, with electronic switching of measurement limits, complete with a 1:10 divider-nozzle. The microprocessor built into the device controls the operating modes of the device when they are set from the front panel and through the KOP interface, performs self-diagnostics of the device. The computational functions performed by the microprocessor are typical for high-speed voltmeters. In addition to measuring voltages in absolute values, measurements are carried out in percent and decibels relative to the set level, the results are averaged over a selected number of measurements, extreme values, duration and other parameters of pulses are determined.
