Hello everyone!<br> <br> I am working with a<strong> DAQ 6510</strong> and a<strong> multiplexer 7700</strong> and I am trying to set up a scan with <strong>two channels</strong> that is <strong>as fast as possible</strong> (channel used: 109,119 - I have also tried a 109,108 pair).<br> <br> I read from the manual that this multiplexer has a switch time between channels of <strong>3 ms </strong>which is just the value I would like to have.<br> <br> Unfortunately, despite the fact that t<strong>he scan is set to reduce accuracy and improve scan speed</strong>, I cannot get a switch time between channels <strong>less than 10 ms</strong>.<br> <br> The configuration, set by <strong>LabView</strong>, has the following parameters: <ul> <li>Voltage DC function</li> <li>External trigger</li> <li>Scan count: automatically setted according to the experiment running time</li> <li>NPLC = 0.0005</li> <li>autozero disabled</li> <li>autorange disabled</li> <li>line sync disabled</li> <li>3.5 digit display resolution</li> <li>no statistics</li> <li>no filter</li> <li>trigger delay = 0</li> </ul> I think the limit encountered is due to a configuration problem according to what is written in the manual (swtiching time limit &lt;&nbsp; 3 ms).<br> <br> Do you have any suggestions to achieve faster scans? Since this value of 10 ms is so repeatable, is there some parameter I am not considering?<br> <br> Thank you!<br> <br> &nbsp;
