Multi-function Counter Frequency Cycle Count Self-Calibration PPM 1Hz-10MHz


Overview:

This multi-function counter is developed and accomplished by using microprocessor technology. It is a kind of precision test instrument. The biggest feature of this instrument is that it adopts inverse counting technology with high measurement accuracy, wide frequency range, high sensitivity and fast measurement speed. It has the function of PPM measurement and the preset frequency F0 can be set arbitrarily. This instrument is suitable for post and telecommunications communications, electronic laboratories, production lines and teaching, scientific research.
