PXI and telemetry

[Juliano]

I wish to make a acoustic measures using NI-4472, but I need to use a telemetry or other wireless solution to connect the sensors (microphones) and the PXI. Is there a National or 3rd-party product able to be installed between NI-4472 and the microphones with minimum signal degradation?

Jeopardy,

I was looking on the web (actually Google) for wireless microphone' receivers. I found a very interesting paper that you might find interesting (see link below):
WIRELESS MICROPHONE SYSTEMS: Concepts of Operation and Design (Lectrosonics)
.
I looked at different receivers in the market and most of them have an audio out signal. This is the signal that you could connect to the 4472 board.

So the same company that makes the wireless microphones would provide you with a receiver. I have not worked extensively with wireless microphones, so I would not be able to recommend a specific brand. I would advice you to look at different wireless microphones providers to see which company offers a g
ood quality receiver so the signal arrives to the 4472 boards in good conditions.

Hope this helps,

In fact, I need precision measurement microphones, not simple audio ones, but thanks for the idea of choosing wireless microphones instead of a telemetry device.
I've already contacted PCB and ACO Pacific to see if they sell wireless precision microphones, and I'm still waiting an answer.
If you happen to know any other wireless microphone provider, please let me know.

Sincerely.

I'm wondering whether there's any update to this post...? Anybody?
