* Amperes - range 0.03mA .. 1A
* Volts - range 0.03V .. 1000V
* The sampling rate is unknown (most probably it can't competete with real 20MHz+ oscilloscopes - unless it should happen to contain a RAM cache)
The advert suggests that one can also use it as audio playback/sampling device (sampling should be possible, but playback may require additional hardware).
