am looking for any example vi's for impact/modal analysis testing. I am

We are still working on a solution - when this is complete, we will post it here.

We seem to have lost contact on this problem - can we still work towards a solution?

Apart from upgrading elements such as number of channels, and other functions, the key step is to export the UFF files into MODENT. (NI generates UFF binary - MODENT needs UFF ASCII)

Is this possible?

I would welcome continue support on this.

Thanks for all your assistance so far.

no reply from contact at MODENT. I will investigate writing a conversion utility from the binary to ASCII version of UFF 58

[dsb@NI]

Here is the conversion utility. Please give it a try.

Here is a previously posted example program that implements a software trigger for impact test.

The software trigger makes it so that the 9233, 9234, 4431, 4432, and other devices with no hardware analog level triggering can all be used for impact test.

The solution works now; allowing NI Labview to export data into UFF Binary, then convert UFF Binary into UFF ASCII, then read UFF ASCII into the MODENT Suite.

Thanks !

Here is a LV example that does Impact Test

Feedback is welcome and appreciated!

above LLB was missing a typedef, and I also had a chance to fix a bug in limit test updates

By the way, if anybody has a chance to start using this, please comment on preferred behavior for saving and loading configuration. As an example, developers can always Make Current Value Default. If building an exe, would you expect a button 'Save Configuration', automatic saves, Prompt on Exit, All of these?

Hello Doug,

You've made a nice program, with a lot of practical features.

I've got only one problem: it doesn't save the measered data. The program does maken an empty result file...

An automatic save option would be excellent.

Thanks in advance!
