Rookie Question about REW Inputs

[EdPetry]

Hi,
New to REW. Reading the available KB and literature I've learned a lot. But I am confused by one thing. Inputs.

I am attempting to repair and calibrate stereo equipment. This requires seeing the two channels (L & R). If I understand correctly this is possible using REW as an upgrade. This upgrade will allow me to see 4 inputs at a time. Is that correct?

Thanks.

The Pro upgrade supports multiple inputs, as many as the interface and computer can support, which depends somewhat on the OS and processor. I haven't had any issues capturing 16 inputs simultaneously. That doesn't mean you need the Pro upgrade though, you can measure each channel independently and the standard version has a scope tool supporting two inputs and the level meters show two inputs.
