Problem with decreasing sample interval

Post by Mustafa » Thu Feb 13, 2020 12:50 pm

Hello Pico Technology Team,

Picoscope 2405A
Python 3.7
Ps2000aStreamingExample.py from the Github Wrapper

I'm getting out a signal from a device as shown in figure 1, Then I'm decreasing the sample interval trying to get 1 signal sample that would look like Figure 2.
Figure1.png
Figure 1
Figure2.png
Figure 2
the problem is that as less the sample interval as less possible to get out the required sample, it gives me most of the times the threshold that looks like Figure 3.

Figure 3
so how can I fix the signal sample to give me the same output every time ?

Thanks in advance!

Best Regards
Mustafa

Hi Mustafa

If you are wanting to have a repeatable capture you would most likely need to use block mode with a trigger rather than streaming mode.
