?High cost, USB Function / Arbitrary Waveform Generators (card) (virtual).
?From the computer using analog sensors and real-world signals, reproducing its waveform.
?Other products can be used as signal generating module, without a PC, power required to generate an arbitrary waveform signal.
?200 MSa / s sampling rate, 12-bit vertical resolution.
?One computer can connect many sources, extend channel easily, generate phase waveform that mimics the three-phase alternating current and so on.
