I have a VISA write in a state machine, and the write was a bit slow. It was taken out of the machine and placed in a seperate VI for timing analysis. Affter the VISA write was placed in a different VI, the write duration decreased by 1s. What reasons could have caused it? Thanks!
The instrument is a precise DMM that connects to a GPIB module in a PXI chassis connected to a laptop through an express card. The command written to the DMM is a string with about 10 characters. We use a flat sequence structure with the tick node and the 1st and 3rd frame to time the performance of the write node in the 2nd frame. I don't have the code. Somebody else is working on it now, but I was pull in to have my brain picked (the NI forum as well). I am just looking for general advise. Thank you!
Refer to my previous post. Thanks!
You need to bring the patient in to get a diagosis.
ok. never mind. He didn't check it into source control. It is on his PC. I will let him figure it out or ask it on the forum himself. Thanks!
