Electronic digital frequency meter CH3-64 / 2
|
Frequency Electronic Digital CH3-64 / 2 for automatic measurement frequency and period of continuous sinusoidal signals and the average value of the carrier frequency pulse modulated signals, time intervals, the pulse duration, the frequency ratio of the two electrical signals, counting the number of oscillations of the electrical signals. & Nbsp ;
is developed to replace cathode-counting frequency meter computing CH3-64 / 1 and may be used in such fields of science and technology, as radar, radio navigation, various communication systems, metrology centers to configure, test and calibrate different kind of electronic equipment. Frequency counter can operate autonomously and as part of the automated measuring systems.
