Joseph167 Posted April 11, 2007 Report Share Posted April 11, 2007 QUOTE(crelf @ Apr 8 2007, 12:59 PM) You're going to have to give us far more information than that:What is the make/model of the LCM? Do you have a link to it's spec sheet? What have you already tried? (post a VI or two for us to have a look at) What sort of DAQ hardware have you got? What sort of signal (details) is the LCM expecting? What version of LabVIEW will you be using? Tell us more about the sine wave and the response you need to generate. I am not sure the model of LCM. The digital feedback may be able to convert all input signal to pure sine wave which is setted by us. I am using PCI 6259 and LCM is expecting a pulse with triangular wave as envelope. I am using LabVIEW 8. Thank you very much. Quote Link to comment
