Embodiment
[0029] A multi-channel sine wave phase standard signal generating device, such as figure 1 As shown, it includes two or more filtering and amplifying circuits, two or more digital-to-analog conversion circuits, two or more waveform memories, and shared logic control circuits, address counters, computers, Human-machine interface circuit and clock circuit; among them, the number of filtering and amplifying circuits, digital-to-analog conversion circuits and waveform memory is the same, and they are used in one-to-one correspondence;
[0030] The clock circuit provides a unified clock signal for the logic control circuit and the computer. The computer provides common timing and logic control signals for each digital-to-analog conversion circuit, each waveform memory and address counter through the common control logic circuit. The computer communicates with the operator through the man-machine interface circuit. Realize human-computer interaction; the computer sends the single-pe...
