Overview

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, gap-free 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. Some models have built-in Rubidium atomic clocks. 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. Pendulum’s range of Multi-channel Frequency Analyzers support parallel and independent time / frequency measurements on up to 4 test objects in a bench-top format – “4 counters-in-a-box”.

Benefits

• Ultra-high-resolution measurements and high-speed graphic analysis enables new measurements, not possible or affordable before
• Parallel multi-channel measurements (CNT-100 series)  Replace up to 4 Timer/Counters with one instrument. Save space and money in R&D.
• Modulation domain analysis gives unique insight in frequency dynamics (TimeView & CNT-100 series)
• Save time, space and money in production test
• A one-box solution for easy and light-weight portable frequency calibration (CNT-91R, CNT-104R)
• Continuously stream and store frequency data for weeks without losing a single cycle
• Get all relevant radar parameters, incl. frequency profile in chirps, in one single unit (CNT-90XL) 
• Outstanding ease-of-use 
• Flexible configuration, upgrade when needed via SW licenses. No risk to overpay or underbuy

CNT-100 series

These new products marks the 5^th generation of advanced Universal Frequency Counters, the multi-channel counters. They feature the brand new concept of Multi-Channel Frequency Analyses, capable of doing 2 or 4 frequency measurements in parallel in a single box. Just as oscilloscopes have been able to visualize 2, 4 or more inputs or decades.

They feature advanced numeric and graphic measurement views; Values with auxiliary parameters, Full Statistics screen,  Time-line (value vs. time) graph, Distribution graph, and live ADEV graph.

The resolution is ultra-high, up to 13 digits/s for frequency, and down to 7ps for time. Measurement speed is outstanding, up to 20 million gap-free frequency samples/s.

Standard Frequency range is DC to 400 MHz, with an optional extra input for either 3 GHz, or 10 to 24 GHz.

The performance can be upgraded via SW licenses at any time, e.g. adding a100 MHz pulse generator output or extending the range of optional input C from 10 GHz to 15, 20, or 24 GHz. The UI is easily viewed and controlled, either on the instrument itself, or via the web interface (wired Ethernet or WLAN) on any connect PC, laptop or tablet.

CNT-90 series 

These products were the pioneers of the 4^th generation of Universal Frequency Counters, the first graphics Counter/Analyzers.

They feature numeric and graphic measurement views; Values with auxiliary parameters, Full Statistics screen,  Time-line (value vs. time) graph, and Distribution histogram graphs.
