Universal counter SC-7217A / SC-7215A TOP

		Maximum 3GHz (SC-7217A) Maximum 12 digits/second display　 Easy-to-use 1 key, 1 action, system adopted. In addition to frequency and period, the universal counter has time intervals, pulse widths, phases, frequency ratios, duty ratios, cumulative counts, and peak voltage measurements, making it easy to perform a variety of measurements. As a basic measuring instrument for development work and technical education, it is also ideal for introduction to production and inspection lines.

	Easy operation with 1 key and 1 action.

	The efficiency of line inspection work can be easily done by the comparison and statistical calculation functions.
	Unit conversion (rotation speed, speed, etc.) is possible with the scaling calculation function.

	Easy to confirm waveform amplitude by measuring peak voltage of input signal

	Improve efficiency of routine inspection work by saving/recalling panel setup

	Equipped with USB, LAN and digital I/O as standard

	Highly expandable option group
	• RS-232, GPIB interface • USB host interface • High stable clock option
