Meter phase difference and the group delay & nbsp; F1-4 & nbsp; provides & nbsp; reproduction precision increments difference between two synchronous harmonic voltages and is used for calibration of gauges spacing phases as well as for setting and studies of various electronic devices that use phase principles information <. / p>

F1-4 principle of the device consists in the fact that any value of the initial phase of the frequency divider input signal having the division ratio N, N corresponds to the possible values ​​of the initial phase of its output signal with steps through 2n / N.
