Voltmeter pulse voltage '' B4-24 / 1 '' since 1989, produced the Minsk plant "Caliber". The voltmeter is designed to measure amplitude and instantaneous values "‹"‹of voltages of repetitive and single signals of pulsed and pulsed modulated forms, as well as variable signals of both harmonic and strongly distorted forms with simultaneous measurement of amplitude and temporal parameters, DC voltages of both polarities. A distinctive feature of the device is a wide bandwidth of 700 MHz with high accuracy (error 0.5%) and measurement speeds of up to 105 meas / s. The device can be used as a high-speed analog-to-digital converter and a signal sampler, and when using an external display and as a wideband stroboscopic digital oscilloscope with the ability to accurately measure the amplitude and time parameters of a signal. A wide dynamic range of voltage measurements (from 1 mV to 1000 V) is provided by the stroboscopic probe attached to the device with dividers - nozzles 1:10; 1: 100 and a remote scale amplifier, with electronic switching of the 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 computing functions implemented by the microprocessor are characteristic of high-speed voltmeters. In addition to measuring the voltages in absolute terms, measurements are carried out in percent and decibels relative to the level being set, averaging the results for the selected number of measurements, determining the extremes, duration, and other parameters of the pulses.
