The input rate can be up to 250 kHz. Zero index error correction and anti-jitter circuitry are provided.
The Counter with Extended Main Board and quadrature signal conditioner accepts encoder signals to display the result as position, length, angle, or rate scaled in engineering units to ¡¾999,999. The input rate can be up to 250 kHz. Zero index error correction and anti-jitter circuitry are provided. Utilizing quadrature for rate can be superior to a standard ratemeter, which may not be able to distinguish between noise and actual pulses.
