 |
|
Hi all,
i would like to know if PS3224 offers a peak detection command to detect the maximum and minimum of signals.
Is it possible to call ps3000_get_streaming_values and then retrieve the max and min values using aggregation? I am using VBA macros in excel to do this.

Hi and thank you for your post. I have conveyed your question to one of our software engineers. In response to your query:
There is no 'peak detect' function as such. Although there are ways to achieve this sort of thing.
Exactly what data you are looking for, is it a single pair of values (max and min) for the entire data set? Do you want to log the max/min across multiple data sets?
You suggests streaming which is slow, are you expecting to have spikes in the data that could be missed by the slow sampling of streaming? If so, how wide are the spikes? Is it acceptable to have breaks in the data, if so then block capture mode might be a better option.
Whichever way you approaches this, you need to write the aggregation routines yourself.
The more information you can provide about what you are trying to measure and achieve, then we'll have a better idea of how to help you.
Kind regards

I have attach the signals that i want to capture specifically. As the signals are automated to repeat every second, and in this second i only want to capture the signals as specified in the attachement. The signals are at 36 KHz and it can be negative peaks(as in the attachment) or positive peaks.

How do i go about doing that?
THanks.
