Acquisition - 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 (michael.pusch@ibf.cnr.it).
Last version:
July 15, 2021 - 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.

files
