Description
PM 6681 - Breakthrough Timer/Counter/Analyzer Performance

With its revolutionary technology, the PM 6681 from Fluke sets the new standard for measurement of time intervals, frequency, phase and jitter. PM 6681 is much more than just a timer/counter. Its speed and resolution are comparable to the most accurate time and frequency modulation domain analyzers. Connected to your PC running Fluke's TimeViewTM software, PM 6681 fully matches the functionality of a dedicated modulation domain analyzer, at a fraction of the cost.

Rubidium Counters

The PM 6685 and PM 6681 are available as R versions with a Rubidium Timebase.


Fluke Rubidium Counters are equipped with a Rubidium reference oscillator. The short warm-up time make them ready for use quickly after field transport or a change of location inside a building. The atomic resonance principle of rubidium standard is intrinsically 100 times more stable than the electromechanical crystal resonator. The built-in rubidium reference solves the practical problems of ensuring very high stability under tough field conditions.
