Hi all, I want to control the HP 438A with python, get power information and plot it over time. This is my first python project and I need just to control power meter and get information as I said before. There is no time to learn step by step the python.
I installed the phton 2.6, PyVISA-1.3.win32 and the software of the GPIB-USB controller. I started the program and wrote this script. from visa import * and the response I received is below. Traceback (most recent call last): File "<pyshell#1>", line 1, in <module> from visa import * File "C:\Python25\lib\site-packages\visa.py", line 1, in <module> from pyvisa.visa import * File "C:\Python25\Lib\site-packages\pyvisa\visa.py", line 231, in <module> resource_manager = ResourceManager() File "C:\Python25\Lib\site-packages\pyvisa\vpp43.py", line 105, in __new__ it.init(*args, **kwds) File "C:\Python25\Lib\site-packages\pyvisa\visa.py", line 227, in init self.session = self.vi = vpp43.open_default_resource_manager() File "C:\Python25\Lib\site-packages\pyvisa\vpp43.py", line 758, in open_default_resource_manager visa_library().viOpenDefaultRM(byref(session)) File "C:\Python25\Lib\site-packages\pyvisa\vpp43.py", line 175, in __call__ self.load_library() File "C:\Python25\Lib\site-packages\pyvisa\vpp43.py", line 141, in load_library self.__lib = windll.visa32 File "C:\Python25\lib\ctypes\__init__.py", line 423, in __getattr__ dll = self._dlltype(name) File "C:\Python25\lib\ctypes\__init__.py", line 348, in __init__ self._handle = _dlopen(self._name, mode) WindowsError: [Error 126] Das angegebene Modul wurde nicht gefunden I wasted to much time to reach the answer of this problem over the google, you know. So, what is the problem? What do you suggest me? Thanks a lot from now on. Best Regards. H.Sinan Aksimsek __________________________________________________ Do You Yahoo!? Sie sind Spam leid? Yahoo!
