Advanced Statistical Analysis and Multi-mode Presentation
The graphic display shows frequency or power changes over time, directly on-screen, providing measurement and analysis of FM/AM modulation, power and frequency changes, VCO settling, post-tuning drift, and more. Built-in statistical processing presents on screen display of frequency/power distribution, frequency/power stability, or modulation; in numeric, trend-line, or histogram formats.
Power steps from a generator (-30 to -5 dBm, in 5 dBm steps). Note the output is turned off between power steps; not something a power meter nor a spectrum analyzer would catch
With TimeView, Modulation Domain Analyzer software (optional), the CNT-90XL can provide a more robust statistical capability, post-processing collected data for in-depth analysis. Multi-functional Frequency Counter with Power Meter

- Outstanding performance/price ratio
Fast Speed and High Resolution
The CNT-90 Frequency Timer/Counter/Analyzer is excellent 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 timer/counter/analyzer outperforms many existing counters on the market. The CNT-90 offers ease-of-use, a multi-mode graphic/numeric display, and improved control over measurements, at a very 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).
Graphic Display and Multi-mode Presentation
The CNT-90 is a frequency counter with 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-90 statistical processing is more powerful and 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 and Time Base
The CNT-90 features a frequency range of 300 MHz standard with options to 3, 8, 14 and 20 GHz. Two OCXO options are available: one with very high stability (0.01ppm/month), and one with an ultra-high stability (0.003ppm/month).
GPIB/USB Increased Throughput and Efficiency
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%.

CNT81 and CNT-81R Timer/Counter/Analyzers
Pendulum Instruments offers a choice of two high-performance timer/counter models; the fast/high-resolution CNT-81 and the CNT-81R with built-in Rubidium time base, which allows frequency calibration of the highest possible specified oven oscillators. The counters are equipped with GPIB-interface as standard, for use in automatic test systems, or in PC-controlled instrument clusters on the lab bench or workshop bench. The standard frequency range of 225/300 MHz can be extended to 2.7 GHz. With the new 8 GHz prescaler input option, the frequency measuring range is extended into 8 GHz. Optional timebase oscillators extend the timebase stability to 0.02 ppm/year. The CNT-81R has a built-in atomic clock standard (Rubidium).
Suitable for Test Systems
The high-performance timer/counters are capable of handling virtually all measurements of frequency, time interval or phase. They include an internal storage of up to 6k values. Measurement speed to internal memory is up to 40k readings/s (8k/s with full resolution). The CNT-80-family of counters has excellent immunity to EMI, which makes them suited for all types of test systems. In the calibration lab they can calibrate time, phase and frequency with ultimate accuracy, speed and resolution.
The CNT-81/CNT-81R are also valuable tools for the R&D engineer, featuring almost every po built-in mathematical and statistical processing, very advanced arming and hold-off functions, modulation domain analysis and much more.
