vrf AW: SCREEN DUMP OF LECROY OSCILLO TO GPIB IN BMP FORMAT WIT

Question asked by VRFuser on Jul 1, 2003
Hello,

I asked this question once in this group, and the best solution I found was
to read byte by byte until an error occurs.
This takes a long time, as there is generated a lot of overhead (every byte
is a single read commad), but it works

Betreff: [vrf] SCREEN DUMP OF LECROY OSCILLO TO GPIB IN BMP FORMAT WITH VEE



Hello all,

I am trying to dump the screen of my oscillo and read the associated bitmap
file with the IO transaction box of VEE pro. On my osciilo, I have set up
the port and the device as "BMP" and "GPIB". Then, from IO transaction box,
I "WRITE" the command "SCREEN DUMP". The oscillo is then sending something
to the GPIB, but I don't know how to read it. I tryied "READ"  "BINARY" in
"BYTE" format in a loop, but I cannot find the end of the file. If I read
not enough data, then the next command is not understood by the oscillo
(GPIB may be busy, OSCILLO may be in talk) and if I read more data then
necessary, there is an error during data processing.

Did someone already dump the screen of his measurement tool with VEE pro?

Elisabeth Yoshida.
