I want to know the amplitude limit protection mechanism of RT-BOX is based on software or hardware?My Sine wave seems a little cutoff distortion or saturation distortion.And my scale and offset settings are as follows.I am a little afraid that my poor settings has damaged the precious and costly RT-BOX.My God!!!

Hello,

You can set the analog limits on the RT Box in the Coder Options window, as shown in the following figure. Just scale and offset the values that you are sending out to be within the set analog output voltage range, and you should be able to see the expected waveforms.

Regards,Manu
