Product Features
The multi-functional phase comparator consists of an X transmitter, a Y transmitter, a Z transmitter, and a main receiver unit. The three transmitters transmit the phase and frequency signals from their respective lines back to the main receiver unit. The main receiver unit then calculates the phase differences between the three lines to determine the phase sequence.
