Frequency Counters/Analyzers

  • Frequency counter analyzer
  • Microwave counter analyzer
  • High performance frequency counter analyzer
  • Modulation domain analysis system

Pendulum brand frequency counters/analyzers are well-known as industry-leading time and frequency measurement instruments.

These products are characterized by ultra-high speed and resolution with advanced graphics, zero dead-time, Allan deviation measurement, modulation domain analysis and overall the highest-performance frequency measuring instruments. Various models offer portability with battery-option and range up to 60 GHz. Software can extend the capabilities of the measurement hardware. An example is the TimeView software package to offer comprehensive frequency analysis in the time-domain.

CNT-90 Timer/Counter/Analyzer Details

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. 

Fast Speed and 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); and 12 digits/sec resolution (frequency). The CNT-90 offers ease-of-use, a multi-mode graphic/numeric display, and improved control over measurements, at a very competitive price.

CNT-90XL Pulsed RF & Microwave Frequency Counter/Analyzer Details

The Pendulum CNT-90XL Pulsed RF Microwave Frequency Counter/Analyzer is an excellent tool for measurement, analysis and calibration of Microwave Frequency, Power, and Pulsed RF time parameters like pulse width and PRI. Whether in test systems, on the R&D bench, in the calibration lab or out in the field, the high-resolution and ultra-fast CNT-90XL is the state-of-the-art Microwave Counter/Analyzer.

The new pulsed RF option enables measurements of pulses down to 30 ns width, plus PRI/PRF, frequency in burst and power in burst making CNT-90XL ideal for radar test and calibration.

CNT-91 Frequency Timer/Counter/Analyzer/Calibrator Details

Ultrahigh Speed and Resolution

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.

TimeView Modulation Domain Analyzer Software Details

Analyze dynamic signal variation of time or frequency with TimeView Modulation Domain Analyzer software for increased advanced statistical analysis including statistical distribution, FFT analysis & smoothing. TimeView is available in two different versions; TimeView 2 that can use any CNT-9x counter and the enhanced version TimeView 3 that requires models CNT-91 or CNT-91R as front-ends.
