Reading data back from HP4195A |
|
|
I am writing a program to control a 4195 over the HP-IB bus,
and I can't seem to find the command to return the data from
a sweep. I have worked with many other HP test instruments,
and usually there is a command that sends back the entire data
set after a sweep is completed (e.g. on the 3562A that command
is "DDAS"). Anyone know would I get the sweep data back from
the 4195A?
TIA!

I don't know about this particular model, but there is a standardized
data acquisition and control language called SPCI (Standard Commands for
Programmable Instrumentation) http://www.scpiconsortium.org/SCPI-99.pdf
which is used by many modern instruments (multimeters, scopes, generators,
etc). DDAS doesn't seem to be a SPCI command, by the way. |

I have an HP3577A that accepts commands like "DRA" (Dump Register A).
Send it "FM1" first if you want ASCII data. If that works, I should
be able to suggest a few more commands to try out.

I know for my HP synthesizer there is a "gate" signal -- and I can control
the synthesizer and spectrum analyzer all in one.
Try posting your question on the newsgroup rec.radio.amateur.homebrew --
there are quite a few former HP (Agilent) engineers who visit there. A lot
of ham radio ops use HP network analyzers, synthesizers, VNA's etc. |

I don't know if I'd call a 4195 a "modern" instrument. My 4195A was
made in 1989, and
SPCI came out in 1999.

It's an HP-IB command that the 3562A accetps.

Have you tried poking around www.agilent.com yet? Of the two (HP or
Agilent) I would suspect that Agilent is more likely to have old stuff
for that. Of course, it may be old enough that the docs were never
done for online perusal...

Thanks very much Mark. I've played around with this a bit, and I found
that the
A register has the Y data and the X register has the X data. But what
data is
contained in the B register?

Hi,
Please contact my friend Marc / F5MM he has many many HP TM equipment and do
some programming for these and he own a 4195A .
His email is: marcmislanghe@compuserve.com
Recommand you from myself, he's a very good friend. He is also starting a
European HP museum with around more than 500 instruments, vintage and more
recent.
I copy him with this email.
Good luck
Pierre-François / F5BQP
