Frequency Counters/ Analyser
Available in the UK from APC Time, Pendulum Instruments’ frequency counters/analysers are well-known as industry leading time and frequency measurement instruments.
These products are characterised 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.
