The frequency counter electronically counting Ch3-88 is intended for measuring the frequency and period of sinusoidal and pulse signals, measuring pulse duration, time intervals, pulse duty cycle, frequency ratio of electrical signals, counting the number of pulses, issuing reference frequency signals. Main functions: measurement of inputs A, C of frequency, period, time intervals, pulse duration with averaging and using an external tag generator, counting the number of pulses; frequency measurement at input B; measuring the ratio of frequencies - channels A / C, C / A, B / C; Low-pass filter, built-in attenuator, indicator - nine decimal places; start of the measurement process - single, internal, external or software; work from an external reference generator; work on the USB 2.0 interface.
