If i turn off the scope and turn on again, it is working good, until i have again this error.<BR />What can i do, help me!!!!!!!!!!!!!!!!!!!!! <BR /> Thu, 06 Jun 2002 10:54:50 GMT https://ni.lithium.com/t5/Instrument-Control-GPIB-Serial/VISA-error-1073807339/m-p/48452#M2827 dos 177 2002-06-06T10:54:50Z https://ni.lithium.com/t5/Instrument-Control-GPIB-Serial/VISA-error-1073807339/m-p/48453#M2828 If this really is a simple timeout, and for whatever reason you are unable to increase the VISA timeout just add a delay between the write and read calls.<BR />something like<BR /><I>int data[1024];<BR />viPrintf(vi, ":WAV:DATA?", VI_NULL);<BR />Sleep(100);<BR />viScanf(vi, "%,1024d", data);<BR /></I> <BR /> Thu, 20 Jun 2002 11:21:43 GMT https://ni.lithium.com/t5/Instrument-Control-GPIB-Serial/VISA-error-1073807339/m-p/48453#M2828 saikey 2002-06-20T11:21:43Z https://ni.lithium.com/t5/Instrument-Control-GPIB-Serial/VISA-error-1073807339/m-p/48454#M2829 How do you program this delay in labview? <BR /> Wed, 12 Nov 2003 10:34:11 GMT https://ni.lithium.com/t5/Instrument-Control-GPIB-Serial/VISA-error-1073807339/m-p/48454#M2829 ansoft 2003-11-12T10:34:11Z
