I understand, but that's my point, it's not interpolated!

The number he's referring to is in units of samples per second. It's not doing interpolation between samples, to achieve a high samples per second, because that's not possible, which is my point. Interpolation results in an imagined value, but samples are measured values.

It would be correct to say that the values between samples are interpolated, but the subject of interpolation isn't applicable for anything mentioned in this comment chain.

Ah you are referring to the 'sps' bit. Ok, but I think the extra sentence is enough clarification of what they mean, even if they're wrong about what the device is doing.

The only time these are interpolating is when they are visualizing, there is no point (hah) in storing interpolated data, you can generate that whenever you want.
