Iwatsu Universal Counters SC-7217A / SC-7215A

A Maximum of 3GHz(SC-7217A), and the Digit Display Greatly Increased to Accommodate a Maximum of 12Digits/sec

The SC-7217A / SC-7215A universal counters provide full capabilities including frequency, period, time interval, pulse width, phase, frequency ratio, duty cycle, event accumulation and peak voltage measuring, with simple operation. They are suitable for R&D and technical training as a basic measuring instrument as well as for production/inspection lines.

Universal Counters

Model:

SC-7217A / SC-7215A

Maker:

Iwatsu Electric Company Limited

Feature

Easy operations with single key strokes for each action.

Making line inspection tasks more efficient is a simple chore with the comparison and statistic calculation functions.

The scaling calculation function enables single unit conversion (revolutions, speed, etc.)

Input signal peak voltage measurements make it easy to confi rm the waveform amplitude.

The save/recall function for panel setup makes predetermined inspection tasks more effi cient.

USB, LAN, RS-232 (option) and full remote control with GPIB (option)

Full lineup of options to provide greater expandability
・ Data stored on USB storage memories.
・ High-stability clock oscillator option.

The display digits for time gate, EXT-B gate, and single gate are listed in the table below.

Gate	FREQUENCY A,B	FREQUENCY C
10 µs gate	7 digits *1	7 digits *2
100 µs gate	8 digits *1	8 digits *2

10ms gate	10 digits	10 digits
0.1s gate	11 digits	11 digits
1s gate	12 digits	12 digits
10s gate	13 digits	13 digits
EXT-B gate	No. of digits is determined based on EXT-B gate time *2
Single gate	No. of digits is determined based on measurement signal	–

*1 EXT-B cannot be selected during FREQ-B measurement.
*2 GATE 1/1000 setting is required for 10 μs gate and 100 μs gate.
