Mr. John,
Yes! This is precisely what I meant:
----->Do you mean that the device itself first outputs the data from the last scan?
So, I want to make sure that any data from the previous scan was cleared. The program I believe is a bit of a mess. So you need not to worry to much about this program but in general I want to make sure that data is cleared from any device. I tried understanding a bit the functions, GPIB Wait, GPIB Poll etc.... but it is not registering in my head! Sorry to say. Any how that is the problem that I have. Thank you for your help. Best regards,
