Multi-Function Frequency Counter PPM FM Meter for Crystal Industry 1Hz~100MHz


Overview:

Multi-function Counter is designed with inverse counting technology, together with 32-bit high-speed processor and high performance CPLD, it realises a variety of practical measurement functions. It has the advantages of high measurement accuracy, high sensitivity, fast speed and selectable gate time. It also has the functions of frequency measurement, period measurement, PPM measurement, staging measurement, upper and lower limit measurement, cumulative counting, etc. It can adapt to large dynamic range signals. It is especially suitable for crystal manufacturing industry, post and telecommunications, communications, radio and television, colleges and universities, research institutes and enterprises and institutions as a frequency measurement instrument.
