DEVICE FOR MEASURING DEVIATION OF FREQUENCY AND VOLTAGE

摘要

FIELD: pulse devices. SUBSTANCE: device has analog- to-digital converter, counter, reverse counters, digital comparator, RS-flip-flops, generator of stable pulses, setters of codes of normal frequency and voltage, AND gates, buffer registers, short-pulse generator, line for investigated signal, "START" line. Device may be used in digital systems for testing quality of mobile alternating current electric power supplies. EFFECT: increased functional capabilities, increased reliability, allowance tests of frequency and voltage in double range with 0,025 percent precision.
