Probably a question for Tom, but others are welcomed to answer too :-)
I've finally got my hands on an HP4195A (0-500MHz and freshly caled) and
also the 41951A impedance set + 16092A fixture. Unfortunately the 41951A
has been badly tempered and the calibration kit (short and 50R ...

Anybody got basic techinfos or/and usermanuals,
service manuals? I do not have logic probes for it.
Anybody got pinouts for these?
Pls respond via mail!

I have a 560A complete with 2 detectors and 1 VSWR Autotester & with
the 6609A sweep generator for sale on ebay. All working properly... If

I already asked this in the TekScopes list on Yahoo, but so far no
one has stepped up to answer it there.
One of my 7S11s (SN B125nnn) appears to largely match the description
in the military service manual I downloaded from BAMA (even though it

The internal lithium battery on my HP54542A digital scope died. I
replaced the battery and the scope powers up again, but needs cal. I
have the service manual and the calibration instructions don't mention
changing the battery. Is there any special procedure that I need to do

Is there anybody that is familiar with the use of this signal generator
? I got one thru eBAY and it seems not to work properly as I can't get
any signal out @ the 86603A RF section.
display is OK... is there a typical procedure to use or am I just

I have a spectrum analyser (Siemens K2001)but alaas it's only for a

My question is it done in commercial Spectrum analysers to shift the to

Bonjour à tous,

I´m considering buying one of these on ebay.
These 2 products seem identical.
Does anyone know what the difference is?
Thanks

The french compagny that made this signal generator ist out of business
for a long time.
I need a spare CPU card and cannot find it thru search engine; any
suggestion ?

I have A6302 Tektronix current probe that shows erratic behaviour.
The overload light is on, and its intensity varies depending on how open the
probe is.
The DC offset is way off, AC output is wild.

I am looking at buying a used Fluke multimeter (either an 8060A or a
77-III) from a local guy and I would like some simple tests I can do on
each meter.  Neither meter has a current calibration so I certainly
don't expect the either to be perfect.  I may send it off for a proper

I have a 16550A with several stuck channels. One of them is always
stuck hi and two other stuck low. I checks the cables on another card
and they work fine. When I boot the 16500B into diagnostic mode, the

my Advantest R3261A spectrum analyzer has a fault in its PSU and I'm
looking for a service manual.
Even a scan of the PSU part will help a lot.

can somebody help us with the software installation floppy disks or an
image of the hard disk for the device?
The hard disk stopped to respond and we have to reinstall the software
on a new one.
