------------------------------

The total documentation set for this system is quite extensive which
is to be expected for a system that cost close to $60,000.00.

I used to have one and it came with several binders that were about 3
inches thick. Just look at the pictures of the system in an old HP
catalog such as on page 454 of the 1984 edition.

Your best bet is probably to watch on ebay, however, Agilent does have
some documentation on their web site. For example:
HP8505A, 8501A and 8503B

 

Does anyone have manuals for the Network analyser 8505A, and the
related Storage Normaliser 8501A and S-Parameters test set 8503B or
know how to find?

Thanks

Hello

Is there anyone who knows where to get a rubber keyboard for the
instrument. I need the 4x4 numeric part.

Re: regarding bluefeathertech ftp and 8568B

John Miles
 

It may not actually be down, but Bruce changed the port number recently for
reasons I'm not entirely clear on. (I wish he hadn't, because while I can
always remember the URL, I will never be able to remember the non-standard
port number that goes with it when I point people towards the site.)
Basically, you have to use ftp://ftp.bluefeathertech.com:50021 now.

The readme file talks about the reqiured chips (four 27256s, 200 ns access
time or better if I remember correctly.) Despite the note I put in there
about 27C256s not working, at least one person was able to use 27C256s
successfully, so your mileage may vary!

Re: HP1652B Logic Analyser ET AL - system disk, how to create?

Mike,

I wanted to thank you and Agilent for doing such a good job with the old
manuals. It is such a treat for those of us who have and still use the
HP/Agilent test gear professionally to also be able to acquire and
economically maintain the older gear for personal use.

Thanks again and please do not stop :-)

Re: HP8559A Display Chip

 

Hi,

The same chipset was used by Tektronix in the DM501A DMM. It might be easier to find a DM501A than the chips.

Good luck,

Re: plastic feet locking strip on HP equipment.

[email protected]
 

$14 for a plastic strip that is worth about $.15? Youch! One of my 8656A was missing the strip also; I think it's a case of people not being careful when they remove the strips (but I did without problem); don't just rip things out... see how they fit first and learn....

One description for it is "top frame plastic piece".
By the early 90s it had become a slightly lighter
color plastic than earlier. A part number is
5041-8802. You can buy them from www.agilent.com, but
cost is rather high at $14. I need one myself, and I
have no clue why these are so easily lost. Usually
there is no need to remove them unless the front panel
is coming out.

Re: CRT part number in HP 85662 display section for 8566A, 8568B

 

Hi Guys,

I have done this with my CR70, and the CRT in my HP8505A.
It works very nicely. I pulled the socket off of the CRT,
and used the universal adapter, which is a bunch of micrograbber
clips, and connected to the filament, cathode, control grid, and
the focus grid for the G2 connection.

G2 needs to be the electrode that is closest to the control grid (G1).

The filament voltage on the 8505 is some where around 4.5V, and is
stated in the manual.

As to the other settings, pick any O'scope tube, a 5UP1, should do.

You will probably find that the emission is way low. Don't worry too
much about that. HP is pretty liberal in what they need. When you are
in the manual restore mode, you hold the button down until the beam current
drops, and then starts to rise again. Read the manual, it helps.

-Chuck Harris

There are a couple of different part numbers for the 85662A CRT, since it

I have a 85662 with a weak tube.

I finally managed to obtain a Sencore CR70 off eBay. I mean I have
bought 3 of the CR70 on eBay over the last 12 months, and the first
2 never turned up! Now cr70's aren't cheap, especially when you are
trying to ship them to Australia. I am so over being ripped off by
dodgy sellers that know it takes longer to ship surface than buyer
protection lasts. Moral of the story, don't ship surface to
Australia.

Anyway, I digress ;) in all the documentation I have, I can't find
the pinouts for the tube.

However, I do believe I have an equivalent part number: 170xb31

Could someone verify this for me?

plastic feet locking strip on HP equipment.

Mark
 

Can someone please advise me what the plastic strip along the top of
circa 1980's HP equipment is called?

It usually covers the screws that hold the front panel on.

It also enables other test equipment feet to lock into the groove.

The strips come in a 3 different sizes, full size that fits 19" wide
chassis, a half width and a quarter width.

Why anyone would take these off and lose them is a mysery to me!

I am trying to find some of these 'strips', any ideas?


Best regards,
Mark.
