I'm using a STEMlab 125-14. I am having a problem with decimation when using the Python API on my device, comparing to the Oscilloscope feature. Specifically, the Oscilloscope seems to filter the signal, while this does not happen when I use the API. See attached plots. Here are some details:
Oscilloscope trace:
- LV setting
- 200 mV/div
- 20 us/div
- 15.625 MS/s (displayed sampling rate... 1/8th of 125 MS/s)
- osc0 as from the "Oscilloscope Forced Trigger" Jupyter example
- osc0.decimation=8
- osc0.filter_bypass has little effect (True or False).
Any ideas would be much appreciated! Thanks
