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, 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. Pendulum’s Multi-channel Frequency Analyzer product line supports parallel and independent time / frequency measurements in a bench-top format.
