Hi all,
just wondering if anyone has managed anything with these analyzers and could share the approach taken and files used?
Basically, looking to sweep the frequency and take measurements to build a curve.
Or would be realistic to take Mr Millet's 8903 work and just adapt/modify to a different instrument...
Thanks

a MANUAL for any of them might reveal good information...
I'd like to see such a thing. 😀
Having a VP-7725 this is a source of constant frustration.
Perhaps there are some GPIB experts who might be able to instruct on generic functions that could dump the data out...
... no idea if Millet's work can be adapted, but if it could, I sure could use it too!
Think he is a participant here, fwiw.

Hi Bear,
the vp-7723a user manual on the web does have the commands listed in section V and VI , probably very same commands for others in the family.
also National Instruments shows a driver for VP7723A, VP7724A
that's all I've been able to find myself.

got a link to that manual?
with the Millet source code, it ought to be feasible to modify that with the specific commands required and use Millet's graphing functions... or so one might think.

HP would be a good source for how to code in GPIB. They were an inventor of the idea for their equipment and worked to make it a Standard. Before it was a Standard it was called... HPIB.
GPIB, being a Standard, the code and signal levels etc are the same on all GPIB equipement to make them universally usable.
The ref manual sources mentioned above will give the GPIB particulars for that instrument (address etc). Note that there is a limited distance (short) on the GPIB instrument to GPIB instrument cable without a repeater-buffer ($$).

paba, tnx for the link.
unfortunately these are the user manuals, not the service manuals.
useful still.

As I suspected from the similarity of features and operation etc -- Panasonic et al THD instruments are designed and serviced/calibrated by Matsushita -- So maybe we have been looking and asking the wrong people (Panasonic) for info/manuals etc.
The manuals state this and even the Panasonic manuals are copy righted by Matsushita Communications Ind - Electronic Measurement Div. [phone 045-932-1231 in Japan]
Thx-RNMarsh

I realize this thread is 7 years old, but I bought a 7725D and received a CD with a scan of the service manual.
I`m brand new to DIY Audio. Is there a manual repository here?
There is no repo here for manuals. There are some on the web (boatanchor Bama Manual Archive is one). I would like a copy to add to my collection however.
FWIW I have on github source code for GPIB programs for Boonton GitHub - 1audio/Boonton-Windows-10: A program for testing the Boonton audio analyzer and Keithley GitHub - 1audio/Keithley-Windows-10 based on the same starting point. For someone with OK Visual Basic skills (better than my poor skills) it should be easy to modify with the correct commands for the Panasonic analyzers. I hope to do that soon for Shibasoku. . .
