I have been looking for a scope for audio work. Mainly I would need this to measure frequency responses and THD. What is the difference between Picoscope 4262 and 5242A for this work? The price seems to be more or less the same, but 5242A has much wider bandwidth so it could be used in other things also. Is there some drawback in audio work if I buy 5242A instead of 4262? Both scopes have 16-bit resolution, so is there some differences in THD-measurement precision? I don't need AWG.
