Experimental Physics and Industrial Control System

Hi Rod,
We have 2500 points per waveform. Our PCs are equipped with COM ports only, no GPIB cards. One waveform is 73,5 KB to be exact. The RS232 connection speed is maximum 19200 Kb/s at maximum. For the time being I just want to check whether the experiment went fine, no false triggering, etc. In the future, I would like to analyze the waveforms in matlab via CA. So this will be handy.
What is the speed of the GPIB interface on Tek scopes, anyway?

Pavel:
Every Tektronix scope I've set up communications with had a 500 point waveform (as well as some substantially larger ones). Presently, I'm acquiring those at 10 waveforms per second (over GPIB). Are you sure that would not suffice for you? Is GPIB an option? Much much faster.

Mark,
A waveform weighs 70kB. 4 waveforms = 280 kB. 280 vs 40. I would have to
wait a couple of minutes till the data is processed. 10-15 seconds for
the screen dmp.

It may be time to back up a step. Why not transfer the waveforms
themselves, rather than a screen dump? There are others in the
EPICS community who have already done that for the scopes you are using.
