The scope functionality is usually pretty pathetic, however. For the MSO-19, 200 MS/s, 50 mV/div to 500 mV/div (good luck with low level signals or high voltages), and only 1000 points memory. The QA100 is only 100 MS/s. This is decent for a logic analyzer, but a scope needs a much faster sampling rate since it's trying to reconstruct an analog signal, one with pretty fast edge rates in the case of most digital signals.
