I am using a HP spectrum analyzer. By using Agilent BenchLink software,
I am able to store the screen in hpgl file or other picture formats.

the spectrum analyzer is old, and I can not export the measurement data
out to csv file. Using the BenchLink, I can only retrieve the screen
image from the HP70004A screen.

I choose to use hpgl for it is vector based, and I hope there is a tool
to convert it to vector file like csv. So I am eagerly looking for a
tool to convert hpgl file to csv files, so that I can do further
analysis. Some modern spectrum analyzer can do such exportion to csv.

Hummmm! I don't know either your hardware or software, but Agilent ne'
HP in other analytical software I've purchased for chemical analysis
always had the ability to export either the raw or the scaled values;
otherwise, what good is the software for real analytical purposes?

I googled 'agilent benchlink' and retrieved some 125,000 references,
most of which require detailed specs of your software.

Also, what interfaces does the spectrum analyzer have? In the olden
days, most analyzers had at least a chart output of some kind, usually
only simple +/- 5 volts. If the analyzer has this, you can cobble
together an analog/digital rs-232 or rs-432 (GPIB in HP terms) interface
to dump the raw data to a pc.

Of course, I might be FOS (hey, it happens routinely!), but given what
I've seen the physics researchers put together with aged analyzer (I are
a engineer), most things are possible if you have a signal.

BTW, what other kinds of text files can you export? It is possible to
parse any kind of text-based file using excel visual basic. If you can
get some arbitrary text file, even a binary file, I would be more than
happy to help with the conversion.
