Universal CounterSC-7217A / SC-7215A

Up to 3GHz(SC-7217A)
Display up to 12 digits/second

Easy operations with single key strokes for each action. Universal counters feature frequency, cycle, time interval, pulse width, phase, frequency ratio, duty ratio, cumulative count, and peak voltage measurements for easy, versatile measurement. As a basic piece of measurement equipment for development work and technical education, they are also ideal for introduction to production and inspection lines.


  • Easy operations with single key strokes for each action.
  • Comparator and statistical operation function make it easy to improve the efficiency of line inspection work.
  • Unit conversion (rpm, speed, etc.) is possible using the scaling operation function.
  • It is easy to check the waveform amplitude by measuring the peak voltage of the input signal.
  • Streamline routine inspection work by saving/recalling panel setup.
  • USB, LAN, digital I/O are equipped as standard.
  • A highly expandable set of options.
    • RS-232 GPIB interface
    • USB host interface
    • High-stability clock option
