NI-DAQ 7 Speed

[urs boegli]

NI says in the latest newsletter NIDAQ 7 is up to 20 times faster than
older version at least for single point acquisitions.
Two questions:
What's about the speed of reading waveforms?
Is this true with older versions of Labview (6.1) too?

Thanks

I am sure NI can chime in on this but yes NI DAQmx is about 20 time faster than Traditional NI DAQ. Ni DAQmx is only available in LV7 right now. LV6.1 uses the traditional NI DAQ. In LV7 you can use both versions. The big improvement is the use of multithreading or the concept of skip if busy when reading. This will allow you to read a waveform 20 time faster because the if you are aquiring 1000 points but only 20 are available the traditional analog input will stop and wait for information even if it is not there, the new daqmx will release and then come back to read again rather then waiting hence "skip if busy". Hope this helps.
