Having some struggles with getting some drivers
together for the HP8757. Have both the C, D and E version. Generally
when you query the instrument, there is typically a question mark (?) at
the end of the query string. To get the number of points that the 8757
is set up in, it indicates that command is simply "OPSP" - no question
mark in sight. I can't seem to
write that with a VISA Write, as it hangs
the bus up. Tried a Read, with same result. I'll then need to read
back that number. When I do Write the "OPSP" string, I get a display on the 8757's
screen indicating it's sending data to the GPIB, but I get back an Error
Code and I have to Preset the instrument to clear the bus.
