Acquisition - Gepulse
Gepulse


GePulse is a data acquisition program for National Instrument boards PCI-6035E, PCI-6036E, PCI-6052, PCI-6221, PCI-6251, and now also several USB interfaces, and for the Instrutech ITC16 and ITC18 boards. The program runs only on the Windows operating system. The program is for free but no responsibility  whatsoever is assumed by the author. The program does not need any special installation or registration. Suggestions and comments are welcome (pusch@ge.ibf.cnr.it).

           
    Last version: April 8, 2017 - 
can be downloaded here: gepulse.zip
    Note: On May 25/2012 there has been an important change regarding the management of the alternative output channel. See development history below.



The program is stand-alone, but severeal dll's are needed which may not be on your computer.

The newest version may require several dll's than can be installed using the following executable from Microsoft: vcredist_x86.exe.


*****************************************************************************************

If you have problems installing the newest version, you can still download the older but fully ok version fom May 13, 2008:

There are two download options:

  Only Gepulse.exe (Version May 13, 2008) (zipped) or 

  exe-file (Version May 13, 2008) including some dll's that might be needed

Development history:

Last changes in GePulse:

01.02.2015: Added seal-resistance window
31.03.2014: Added "DoNothing time" command
04.04.2013: Corrected negative leak delay behavior
19.11.2012:  Two changes:
          1. Filtering is now done immediately without waiting for the end of the sweep.
          2. Baseline subtraction implemented. This is valid for the display of traces and the online analysis.

25.05.2012:  Two changes:
          1. The scaling of the alternative output channel is now indeed taken as specified in the settings file
          2. The use or not of the alternative output channel is now specified for each stimulation sequence and not any more in the general settings file. The scaling continues to be specifed in  the general settings.
