Re: Oversampling problem

Hi Hitesh, Thank you for your reply. The 1e9 is to convert ns to s, assuming we use the "interval" value returned by ps4000GetTimebase (timeIntervalNanoseconds parameter). Therefore the expected number of samples per sine period is 1/f_waveform/(interval in s) or 1e9/f_waveform/(interval in ns), or ...

Oversampling problem

Hi, My aim is to get a waveform sampled at 7.8125 MHz using the oversampling feature in order to enhance vertical resolution. Therefore, I tried to set the sampling frequency to 125 MHz, and use oversample=16. I connected channel A to a 120 kHz sinusoidal waveform generator. We have a picoscope ps42...
