I want to use the oscilloscope and the waveform generator simultaneously in MIM. For my experiment I do need both output ports from the waveform generator, but in MIM I get access only to one of the output ports. Is this a bug or is for the moku:lab limited to only one output port generally while using it in MIM.

Hello,  
For the Moku:Lab, you only have access to one output port for the waveform generator in Multi-instrument mode. On the Moku:Pro, you have access to two output ports. I hope this helps!
