  • Support calibration of the output channels.

  • The output signal can be looped back partially (i.e. only one channel while the other channel can be used for field input) or fully (i.e. both channels), via the software itself, to the input of the oscilloscope for display and analysis in real time. Synchronized operation between the Signal Generator and the Oscilloscope with timing accuracy in the same order of the sampling frequency is also supported. It is possible to specify when to start the Oscilloscope after the Signal Generator is started.

  • It is possible to add a mask with specified periodic on/off timing to the signal to be output so that a burst-type signal can be generated. You can choose whether to phase-lock each burst.

  • The waveform displayed in the Oscilloscope can be played or cyclically played.

  • Supports Multilingual User Interface under Windows 2000, XP, 2003, Vista and above. Currently supported languages are English, French, German, Italian, Portuguese, Spanish, Russian, Simplified Chinese, Traditional Chinese, Japanese and Korean.
