I'm using the DSO9404A oscilloscope as a pulse counter. I trying to build statistics from measuring the mean of many measurements of pulse counting. My problem is that the scope only takes under account measurements when there is at least 1 pulse inside the measured interval. When it sees a measurement without any pulse in it, it adds a question mark ('?') near the mean value and write 'Edge?' where the current value should be written. I would like it to also take under account those measurements: write 0 near the current value, add it to the mean and increment the number of measurements. Anyway to define this in the scope?
