Description: Refurbished PM 6666 is a low cost timer/counter with high accuracy frequency, time and voltage measurements that also offers 100% programmability including trigger level and sensitivity settings. A bus learn mode is provided to speed and simplify programming. The PM 6666 is also a bench-top use; with 9 front panel selectable measuring functions including voltage max /min measurements.


The PM 6666 has Volt peak measurements up to 50 MHz.  When displaying Vmax. / min. measurements, positive and negative signal peaks of the input signal are shown simultaneously with a resolution of 20 or 200 mV.


 High Resolution The PM 6666 can measure low frequency signals to high resolution with synchronized multiple period measurements and computing the reciprocal values.

Resolution is at least 7 digits on a1s measuring time, because the traditional ± 1 input cycle error is eliminated. Time interval measurements are high resolution as well as high accuracy, due to the time interval averaging technique. The 100 ns resolution is improved by a factor vN (N = number of time intervals averaged) when compared with single time interval measurements.
