novicelabview Posted November 17, 2014 Report Share Posted November 17, 2014 Hi all, I have a case in which I want read in a signal analog input (voltage) from a photodiode, I want to create a 2 sinewave signal locked in with same phase as the input signal and output them as analog output to my 2 laser diode. the frequency of the input signal is low aroud 15 Hz , the 2 output signal i want to be around 120 hz and 150 hz . I am using USB - 6003 daq card. I have created a vi to see the input signal but I dnt know how to create 2 signal from the waveform generator locked in the phase same as the input signal. I have seen a PLL vi , but dont know how to use that with my program. can any one tell me how to proceed. thanks Quote Link to comment
