Acquire multiple triggers with ADP3450

[JerryM]

Hello, is there a way to acquire multiple triggers with the ADP3450? I am currently using it in Linux mode. When using it in "scope" mode, I would like to be able to start the acquisition, wait for the ADP3450 to acquire N triggers, and then read the entire data from the ADP3450. Looking at the SDK, I don't see an option for this. Looks like I can only acquire 1 trigger per acquisiton. Thank you!

Hi @JerryM

Deep capture buffer and device buffering are available in Standard mode.
For custom application/script it can be enabled with FDwfAnalogInBuffersSet.

Hi @attila, thank you! I don't see FDwfAnalogInBuffersSet on the SDK documentation, is it documented somewhere else? Unfortunately, I get this error when I try to use it 

File "/home/digilent/WaveForms-SDK-Getting-Started-PY/WF_SDK/scope.py", line 87, in open
    if dwf.FDwfAnalogInBuffersSet(hdwf, ctypes.c_int(n_acquisitions)) == 0:
  File "/usr/lib/python3.7/ctypes/__init__.py", line 369, in __getattr__
    func = self.__getitem__(name)
  File "/usr/lib/python3.7/ctypes/__init__.py", line 374, in __getitem__
    func = self._FuncPtr((name_or_ordinal, self))
AttributeError: /lib/libdwf.so: undefined symbol: FDwfAnalogInBuffersSet

Hi @JerryM

Which software version are you using?
This feature was added in 3.20.26

Ok I see. I am using 3.17.1. I am ssh'ing to the ADP3450 and running the script from there, I guess that was the version installed by default. I'll try to upgrade!
