Now i used the NI-FGEN and NI-Scope and when i see the help file it said "wave form saved with scope soft front panel can be played back using an NI arbitary waveform generator and the NI-source-SFP V 1.1" but i dont understand about that, please tell me how to play the wave form back for the example i want to save wave form about 10 min and then i want to paly it back, thanks you for your kind
