Delay-problems with Tektronix TDS 2014

[pathman]

We have downloaded the drivers for Tektronix TDS 2014 and connected the oscilloscope with a signal generator. We are using 5 or 6 different vi's, but the "Read Waveform To Array.vi" and "Read Waveform to File.vi" is using more than 6 or 7 seconds. The other vi's are quite fast. What could be the reason for this delay? We need our program to respond a lot faster than this, so we hope someone can help us! Thank you in advance!

Some of the time spent would certainly depend on the size of the waveform you're transfering and to some extent on the actual gpib board you're using (older and cheaper gpib boards have a slower transfer rate). The VI is also doing a few other things besides just the waveform transfer. It is requesting the waveform preamble each time and you might want to try skipping that and just issuing the CURVE? command to see how long it takes just for the waveform transfer itself.
