    thank you for your explanations. I was thinking if the 407 could send a
pair of big serial streams over the RS232 so I can see it on PC. The 2000
points of memory you mention is only for showing the trace on the CRT or is
the same memory that's sent to the PC?

    Yes, I would also prefer the 1507. This is only a question of money.

    Thanks,
