Method and arrangement for measuring and indicating the frame rate of monitors

摘要

The usual measurement of the frame rate using an oscilloscope presupposes either an intervention in the interior of the monitor or a separation of the monitor cable for obtaining the measurement signal. To avoid this disadvantage, the invention provides a method and an arrangement in which the brightness fluctuations corresponding to the frame rate are converted into electrical pulses with the aid of an optoelectronic component and then counted in a frequency counter and the instantaneous frequency is indicated on a display device. <IMAGE>
