FAQ

+ Can I adjust the corner frequency of the low-pass filter?

Yes! It is adjustable from 237 mHz to 3.98 MHz via the iPad.

+ What is the maximum rate at which I can save data, and how many points can I save?

The sample rate is dynamically adjusted by the horizontal zoom of the display, and can be set up to the full ADC sample rate of 500 MS/s. Currently you can save 16k points for two channels simultaneously.
