Subject: RE: HP (Agilent) 85869PC software


Mr Price 
Thanks for the reminder, I had forgotten that the HP graphics language had
an Office filter. Good quick and dirty solution. But, I believe that the raw
test data, not image data, should be archived. Image file data is "volatile"
and frequently is not portable across different versions, platforms, etc.
It is difficult to beat the simplicity and reliability of an ASCII text
file, in engineering units, with a CRC appended.
luck, 
Brian


Brian:

The HP-85869 software doesn't allow you to get at the "raw" data! Many
times, I would have liked to print out a data sheet with columns of
frequency, raw data, cal factor, cal loss, probe factor, corrected
amplitude, limit value and dB over/under.

The last revision of the 85869 added access to a subroutine that lets you
archive ALL the peak freq/level pairs to disk, but this is a disconcerting
thing to do (you need to PAUSE the 85869 program, type in a command in the
command line, execute it, and then CONTINUE the 85869 flow). If you mess up,
you lose the data acquisition run, don't collect $200, and go directly to
the Santa Rosa jail. <g>

BTW, there are several graphics converters and viewers that have HPGL (or
HPCL) reading ability. Unfortunately, every one I tried has one or more
strong negative aspects when trying to convert an HGL to a JPG or BMP. The
MS Word patch is the best solution that I found.

Regards,

Ed
