Hi,
I want to dump the spectra taken by a Network Analyzer HP3577A into a PC
using a GPIB interface. I'd like to do it with labview. I found some
labview drivers on the web but no one works. I have been working on this
problem for days but I do not manage to find any satisfactory solution.
I'm wondering if someone has already faced this problem and resolved.

"The HP3577A can provide a hardcopy of the CRT screen without a computer.
It does this by direcctly controlling a digital plotter connected to the
HP3577A's HP-IB port located on the rear panel. The plotter (such as the
HP7475A) must accept Hewlett Packard Graphic Language (HP-GL) commands. The
HP3577A must be configured in a Talk Only mode and the plotter must be
configured as a Listen Only device. Refer to SPECIAL FUNCTIONS in the
Reference Section."

If it's HP-GL instead of writing to a plotter, write to a text file.

Here are 2 Examples from the USER Manual which I OCR'd

100!
110! Controller responds to plot completion by polling the bus
120! CONTROL lines (SRQ-1024) pulled by the instrument's EOT

Hi Pierre,

I have the same problem, do you still have the solution for it? I would like to get the data not just the screen, this is possible?

Thanks very much
