1. PRODUCT INTRODUCTION
1-1.
Description
The GFC-8010H frequency counter is a general-purpose counter
with a measurement range from 0.1Hz~120MHz and 20mVrms
high input sensitivity. The incorporation of the most updated
semiconductor techniques develops a compact, high performance,
highly reliable and high resolution instrument.
