Multi-Function Frequency Counter 1Hz~100MHz Adapt to Large Dynamic Range Signals

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.

Features :

• Microcontroller control
• Equal precision measurement
• Measurement speed 20 times / sec
• Cost-effective, high reliability
• PPM FM meter for crystal industry
• Upper and lower limit measurements
• A-channel with low-pass filter and 20-fold attenuation
• 12-digit LED display (9 data digits, 3 index values)
• Counting options (keyed, gated, external gated)
• Optional RS232 interface, USB interface, RS485 interface
