Delay Signal Counter
Product Overview
The delay signal counter is an instrument widely used in scientific research fields such as high-speed signal analysis and control, precise delay adjustment, and trigger-based counting. In recent years, with the development of quantum cryptography, the delay signal counter has become an essential tool for experimental studies on quantum signals.
The WT-DSC series delay signal counter primarily provides delay and counting functions. The device supports multiple standard levels—including LVTTL, LVPECL, NECL, and CML—as well as custom-level inputs. The counting circuit uses a clock crystal with an error of no more than 1 ppm, and the maximum counting frequency can reach 1.25 GHz. It supports adjustable delays ranging from 0 to 27.5 ns, and the delay channels can output signals at either LVTTL or LVPECL levels.
