Data logger

One of the first version of data loggers for the BE group. It is using a Measurements Computing boards with its UC library. (an early version)

The application is using the driver to get a value for each channel independetly. This would make the app quite inneficient for a large number of channel. The later versions woul use a new version of the driver capable of reading a predefined number of channel at once. Maybe not the best program I made in years.

Well this is nothing new. Just few things: I was taking measurements on CIRIS, hence the graphs and I've added a third tab called scope utilities which as the name says is just a way of saving waveforms from the scope. Just one  060829_1 060829_2 060829_3

I'm not sure this is the chronological developement but on July 2006 I had finised up a new software version for the hairpin probe. This one would also use the HP microwave and the TDS oscilloscope as it can be seen in the  screens. What is new in this version is that is already calculating the electron density although it is saving all data collected. All the data is kept in memory until the program stops. This will lead to a buildup of memory required by the program to run. An inefficient way of writing software I will find later on. Basically here are two main programs. One which determines the electron density in steady state mode and one in time resolved mode. they are switched by a tab control (bad choice also found later). Note the intensity chart (2nd picture) which I use to display the 3d graph of density in time. Maybe I'll find one which has a graph on

This is the first hairpin software. It was written in October 2005 using labview 7 or 7.1 I'm not sure.

It uses GPIB protocol to control the HP microwave power supply as well as the TDS tektronix oscilloscope. It only saves the data files without any computation of the electron density


An app a day

Or maybe a nap a day.

I've decided to list all apps I've done even thought I'm not using them anymore. Just to remind me how I've learned Labview.

I would not upload the actual app but some screenshots and some explanation of what the app does. I don't want to get in trouble in making public a piece of software which is covered by some patents or patents trolls.

If you think the app would be usefull for you contact me and we can arrange something.
