Description
High Accurate Universal Counter Time Measuring Equipment with 100MHz to 1.5GHz Overview : High-precision general-purpose counter is a high-precision frequency and time measurement instrument developed by our company. It takes the high performance AVR microcontroller as the core, and carries out function control, measurement timing control, data processing and result display. It adopts countdown counting technology to achieve equal precision measurement in the whole range. In addition to the measurement functions of frequency, period, time interval, pulse width, duty cycle, phase and counting, it also has the calculation functions of multiple frequency averaging, maximum value, minimum value, standard deviation, Alam variance, maximum deviation (maximum value minus minimum value), single deviation (minus preset value) and PPM measurement. The instrument is equipped with an externally triggered external gate function that enables rising edge triggered measurements (for time measurements) and positively gated frequency measurements (for frequency measurements). The internal clock frequency is 150MHz. The machine has stable performance, complete functions, wide measurement range, high sensitivity, large dynamic range, high precision, small size, easy to use and reliable. In industrial production, scientific research measurement and other fields have a wide range of uses, is the traditional electronic counter ideal replacement products.
