There are too few sample points for Sin(x)/X interpolation. --- Quote from: Carrington on January 07, 2014, 06:58:05 pm ---And no idea why this happens: :-// --- End quote --- |

Hi All To Help show how DS2000 makes vectors out of sample points. I have constructed waveform files that have a low number of sample points. The sample points are calculated perfect sin values. I have chosen repeating patterns. I show 6, 4 and 2.5 sample points per cycle and at 1GSa/s. You can see how the DSO interpolates the sin in the vector displays These are stopped displays, In run mode the varying trigger scanning causes the sampling to collect a series of sample along the sin display and if not a sin wave(step function) the DSO will create a sin wave overshoot. Note : At 2.5 samples/ cycle the frequency will be accurate but Vpp is NOT. AS EV says very few points |
