With its revolutionary technology, the PM 6681 from Fluke sets the 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 TimeView™ software, PM 6681 fully matches the functionality of a dedicated modulation domain analyzer, at a fraction of the cost.
Every measuring function you need
No matter what measurement function you need for totalizing, frequency or time-related measurements, you'll find it in the PM 6681 timer/counter. The counter gives you no less than 8 totalize modes, including simultaneous up/down counting and totalizing over a preset time. It also gives you a 4 digit 120 MHz peak reading voltmeter plus phase, duty factor, Vmax./Vmin., pulsewidth and rise/fall time.
The PM 6681 timer/counter spans a frequency range of up to 8 GHz, which enables calibration of microwave links, communications and radar equipment. You can make frequency measurements accurately and easily, not only on continuous carrier waves, but also on burst signals.
With the high resolution/speed performance of 11 digits/s, these counters are ideal tools for frequency measurements on telecom systems. Time interval measurements down to 1ps average and 50 ps single shot are supported
