So what is the official noise spec??????

Hi, I bought three Picoscope 3424 units recently. I was quite dismayed to notice that the residual noise of these units is quite big. On all of my units there seems to be random noise with amplitudes ranging between 5 and 8 resolution steps (Inputs shorted). With the units set to +-5 volt range, the...

Oversampling theory

Hi, Thanks for the reply. I think I still may have a problem understanding the theory :oops: : What is the difference between sampling at say 1000ns per sample taking 1000 sample points with an oversampling factor of 2, and sampling at 500ns per sample taking 500 samples with an oversampling factor ...

If I understand the manual correctly, the unit is supposed to take more than 1 sample per sample period (2 for an oversampling factor of 2) and the...
