LabJack Support Posted February 22, 2008 Share Posted February 22, 2008 You can only have 1 stream per device, and the stream is at 1 scan frequency. Link to comment Share on other sites More sharing options...
AzeoTech Posted February 22, 2008 Share Posted February 22, 2008 You may, however, be able to simply oversample the slower scan rates. Basically, if you want to scan input 0 at 1000 hz, but input 1 at 500hz, set the LabJack to scan at 1000hz on both channels 0 and 1, then in DAQFactory, average input 1 down to 500hz. You can use the Avg column of the channel table, but this is slightly limiting in scan mode because of the way data comes in, so you might get slightly unpredictable results. But, if you get the right results, it should be consistant. There are plenty of other ways to down-sample the data as well, depending on whether you want it down-sampled just for logging or for everything else (display, control, etc).

tania Posted February 25, 2008 Author Share Posted February 25, 2008 ok..i never knew it was one samplefreq per device..thnkx..the downsampling is a good option... i wanted to know about the synchornisation of the signals..say 8 channels.... example_: i did all the setups configuration ......all is set..and i leave the safe mode.... can i be able to get the 8 channels at the same time frame...?does labjack be able to handle the signals at the same time frame... and ......daqfactroy acquire signals at the same time frame??
