CNT-91 Timer/Counter/Analyzer

The CNT-91 Frequency Timer/Counter/Analyzer, is the highest performance counter for measurement, analysis and calibration of frequency, time interval and phase. In production test systems, R&D, calibration lab, or in the field; the CNT-91 outperforms any counter on the market for speed, resolution, statistical analysis and processing capabilities.

The CNT-91 provides high 50 ps single shot time resolution or 12 digits/sec frequency resolution for capturing very small time and frequency changes. And, displays up to 14 digits on values obtained. The CNT-91 Timer/Counter/Analyzer also processes an exceptionally fast 250,000 measurements/sec to internal memory with a maximum of 3.5M measurements stored.

Pendulum Instruments frequency counters supports unique graphic presentation of results including histograms, trend lines, and modulation. On-screen statistical processing of random signal distribution and measurement changes vs. time, from slow drift, to fast jitter and modulation. Complete analysis including mean, min., max. p-p, standard deviation, and Allan deviation are viewable in both graphic and numeric format.

With TimeView, Modulation Domain Analyzer software (optional), the CNT-91 statistical processing is more powerful and provides expanded analysis capabilities.

Unlike standard gated frequency counters, the CNT-91 provides continuous time-stamping of events capturing all individual periods, back-to-back without dead-time, measuring every complete event cycle without event interpolation errors. This process allows for a least-squares linear regression of multiple measurements, adding 3 or more digits to the measurement resolution.
