Hi .... I read that DCOM is generally faster because there is little parsing of the out going messages from the host like there is with GPIB. I have an application where I will be looking at a single trigger then 2 points and adjusting the dut based upon this. I know that it greatly is dependent on IF and sweep speed but the best I seem to do is about 16msec/cycle ->trigger then read. I am getting blazing speed when there is a large group of data say 32000readings/sec but that comes from large swept 16001 points. does adding a bridge to the lan help - any suggestions?
