It just means that the input voltage is just amplified and placed on the deflection plates of a cathode ray tube, rather than being digitized, stored, and then displayed at some later time.(as it would be in a DSO or Digital Storage Oscilloscope) Sean P.S. As for whether or not I ought to make it look like a CRO, I'd love to, but I have several problems with doing than (i.e. input bias current on the input buffer is several uA, which would cause too large a DC error if source impedance is >10k) Also, I am mainly doing this a project to learn about high speed ADCs and RF amplifier/attenuator design, not really to market it.
