Data Acquisition form single precision to binary format

[macchia]

Hi everybody,

I work in an Astrophysics group and I'm developing an acquisition system of signals generated by X-Ray detectors (Transition Edge Sensor).

I'm trying to save data acquired by NI-PXI 6132 (DAQ-mx software in LabVIEW 8.0) in binary format.

To do this, I use the 'Write To Measurement File' procedure.

I don't know how it is possible to change the precision from the DBL to SGL directly from DAQ-mx, but I solve this point by creating a 'For Loop' inside my VI, after the data is acquired.

The problem is that I try to save the SGL data with the previous procedure but the 'Convert To Dynamic Data' automatically occurs, and the data are saved in binary format but in doube precision. So, the previous conversion that I made from DBL to SGL does not work.

How can I solve this problem?

Thank you for your help!

Ciao,

Claudio!

Hi Alessio,

thank you for your prompt reply!

In attach there is the VI you reqeusted me.

I was wondering if you were able to solve this problem? Also, without having to use the lower level DAQmx vi's.
