Tektronix FCA3020 Timer/Counter/Analyzer

Overview

The Tektronix FCA3020 is a versatile timer/counter/analyzer that combines frequency, period, and timing measurements in a single instrument. With industry-leading resolution and fast data acquisition, it delivers accurate signal characterization for applications ranging from component testing to system validation.

The instrument includes advanced analysis features such as measurement statistics, histograms, and trend analysis, enabling engineers to quickly identify signal characteristics and verify system performance. Its fast throughput—up to 250,000 measurements per second—reduces test time significantly compared to conventional counters.
