CNT-90

Fast Speed & High Resolution
The CNT-90 is a high-performance frequency counter with a fast measurement speed to 250,000 measurements/sec, with a memory depth of 750k to internal memory, high resolution of 100 ps single shot (time) & 12 digits/sec resolution (frequency).

The CNT-90 offers ease-of-use, a multi-mode graphic/numeric display & improved control over measurements, at a very competitive price.

Graphic Display & Multi-Mode Presentation
The CNT-90 is a frequency counter with graphic presentation of results including histograms, trend lines & modulation that provide an understanding of random signal distribution & measurement changes vs. time, from slow drift, to fast jitter & modulation.

Complete statistical analysis including mean, min., max. p-p, standard deviation & Allan deviation are viewable in both graphic & numeric format.

With TimeView, Modulation Domain Analyzer software (optional), the CNT-90 statistical processing is more powerful & provides expanded analysis capabilities.

Zero Dead-Time
Unlike standard gated frequency counters, the CNT-90’s 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.

Microwave Frequency Range & Time Base
The CNT-90 features a frequency range of 400 MHz standard with options to 3 / 8 / 14 & 20 GHz.

Two OCXO options are available: one with very high stability (0.01 ppm/month) & one with an ultra-high stability (0.003 ppm/month).

GPIB/USB Increased Throughput & Efficiency
For PC connectivity, USB and GPIB (IEEE 488.2) interfaces are standard with the CNT-90. The GPIB interface is SCPI/1999 compliant & 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%.

Battery Option
The CNT-90 and CNT-90XL have an optional battery pack with 90Wh capacity, capable of mains-free operation for at least 4.5 hours. In stand-by the battery pack can keep an OCXO warm and running for over 24 hours
