Limit in waveform data size?

2004-05-07 Thread Carnivorus
Here is the situation: I have to process files which contains records. These records contain data of the waveform datatype. I need to append the record to eachother, using a (while)loop, appending the Y values only as the rest of the attributes and values are the same. The problem: If i try to

Situation: A PC with 2 NI-DAQ cards installed. A NI-6052E and a NI-6040E, the cards are linked to eachother on RTSI bus. The cards are set up to be synchronised for continuous sampling. Problem: When i start reading data with DAQmx READ from both cards, i notice that starting from the first

Answer is already found. The problem was caused by the Timestap that is linked to the waveform data. With the same signal applied to both cards we noticed that there was an exact match in signal form but a displacement in time. When setting the t0 of one signal equal to the other wenoticed the
