Very nice product. I am looking for a digital oscilloscope too, but those instruments in Brazil costs to much. I am a little confused, this produtc says it makes 20M samples per second, but have a analog bandwidth of 250k Hz. What is the greatest (in frequency) signal I can measure with it? Someone knows?
