The CNT-90 timer/counter/analyzer, offers the ultimate tool for measurement, analysis and calibration of frequency, time, or phase. In production test systems, R&D, the calibration lab, or in the field; the CNT-90 is the state-of-the-art timer/counter/analyzer that outperforms any existing counter on the market. The CNT-90 is the world.5s fastest timer/counter/analyzer offering unique ease-of-use, a multi-mode graphic/numeric display, and improved control over measurements.5all at a competitive price.
The CNT-90 features fast measurement speed of 250k measurements/sec with a memory depth of 750k to internal memory; high resolution of 100 ps single shot (time); and 12 digits/sec resolution (frequency).

The only frequency counter with unique graphic presentation of results including histograms, trend lines, and modulation; that provide an understanding of random signal distribution and measurement changes vs. time, from slow drift, to fast jitter and modulation. Complete statistical 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-90XL statistical processing is more powerful and provides expanded analysis capabilities.

Unlike standard gated frequency counters, the CNT-90.5s continuous time-stamping of events enables capture of 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.

The CNT-90 features a frequency range of 300 MHz standard with options to 3, 8, 14 and 20 GHz. All models are available with optional internal OCXO time-bases for applications requiring higher measurement stability. Two OCXO options are available: one with very high stability (0.01ppm/month), and one with an ultra-high stability (0.003ppm/month).

For PC connectivity, USB and GPIB (IEEE 488.2) interfaces are standard with the CNT-90. The GPIB interface is SCPI/1999 compliant and includes a switchable HP53131A emulation mode, for easy inclusion in test systems designed for older model counters, eliminating the need to re-program system commands developed for the 53131A, when replacing these older counters with the modern CNT-90.
With a fast bus transfer speed of 2k measurement results/sec. (GPIB or USB), the CNT-90 saves test system time by increasing throughput up to 90%.
