I am now tryng to acquire a signal(sin wave) using NI9215 in compactDAQ and just to output its signal through NI9263 also in the same cDAQ using a Labview wihch is running in WindowsXP PC. Final purpose is to apply some filtering usch as low pass filters and so on, then to construct a closed loop feedback system whose unity gain frequency is about 0.1Hz.
However, the output sin wave signal lost its values, partially.
In detail, a part of the acquired sine wave data, whose sampling number and sampling frequency are defined in the property of NI9215, can go through the NI9263 and can be detected using, such as, an oscilloscope. But, its successive sine wave data was lost for 130msec, then the next acquired sine wave data appears from the NI9263. This cycle is repeated. I am annoyed with this ploblem
I have few knowledge about Labview, so I am so happy to obtain any kind of informations about this problems.
