NI-5640R Frequency Translation VI (TX portion) times out

[bc2007]

Mauricio,

I'm using the Frequency Translation VI as the template for our project. The VI RX's (port 0) a modulated CXR from an external source and then TX's it back out port 0. This all works fine except after approx. 170 secs the TX portion stops (no output). The RX portion is still RXing but no TX.

I have varied all the parameters that I thought could effect the TX, but the problem remains.

Any idea what could be causing this?

Tks,

Jeff

Seems this is caused by your while cycle I32 iterator. Do you use it? Let's calculate. I32 max positive value is 2^31 = 2,147,483,648. Dividing by 170 secs we have approx. 12,632,256 Hz. Very close to 12.5MHz, main clock divided by 16
