Upcoming Scrounge, Southern Cal.

This is being posted to: TekScopes, HP, TestGear, and CCTech lists.

Fellow techies,

	I'm going to have a day or so of opportunity to do some serious scrounging in the southern California region, specifically around Anaheim and vicinity, coming up in May of this year.

	Being that I haven't been near the area since 1993, I could really use some pointers on who's who in the electronic surplus arena that would be worth a look. My primary interests are in test gear (usually RF and telecommunications, but I keep an open mind), specialized hand tools for connector crimping (both mil-spec and commercial), and "legacy" telephone equipment from the Bell System/Western Electric heyday.

	So... Let the suggestions fly! ;-)

	Thanks much.

Thanks James,
I was hopping to find someone that may have run into a similar problem.
I hate paying for service manuals that don't include data for the most
important element of any equipment The POWER SUPPLY or photos that are
unreadable. My grand kids could have done better with crayons. Back in
the days when Motorola came out with the Quasar, (a modular system )
they still provided schematics for troubleshooting. A technician could
continue to learn and be more than a module changer. Sorry, enough
Venting. Do you know if the schematic and photos are any better on the
$25.00 manual you mentioned.

Hello

I wonder if anyone has had success using Intuilink / Excel with a none HP usb_gpib adapter.

I have comms with my instruments using the test application that came with the lead but now need to be a bit more adventurous.

I'd be grateful for pointers from anyone who has been down this track before.

TIA

Regards Paul

Pat,

A good place to start is the agilent website. They have made available 100s of manuals for obsolete equipment. The 54110D manual is available at:

This service manual does not contain schematic, but it does contain some detailed troubleshooting information.

The schematics are available from:

www.artekmedia.com

You need to get:

54110D    $25.00 (3 Vol. Set, Oper., Pgmr., FRU service, Ext Service)

Even with this there may not be any schematics for the monitor assembly. I have a 54111D and I believe that the monitor assembly was purchased as a component.

I hope that this helps.

Regards,

John Barnes VE3XRY

I'm in need of help with my HP Agilent 54110D 1GHz scope … No Video
but can see a brief flash as High Voltage enters CRT and when turning
off. LED on first power supply board is lit but no other voltages
present on any other test points. Have no service manual ….any help
would be greatly appreciated.

Thanks Pat

Re: INPUT RC NORMALIZER

#5521

you  can  measure  scope  input  capacitance  using  a   capacitance  meter   or  bridge  
just  remember  to  take  the  capacitance  of  your  test  leads  or  coax  into  account.
i  normally  just  measure  the  capacitance  with  the  test  coax  disconnected  and  then  with  it  hooked  up
the  1m ohm resistor  shouldnt  change  the  reading  significantly.
thats  what  the  130 lc  meter  was  designed  for   .
ive  seen  them  used  as  general  purpose   measuring  devices  too.
as  you  know   the  compensator  will  act  as  a  2x  attenuator  when  driven  from  a  low  impedance  source.
you  should  terminate  the  pulse  generator  before  the  coax  enters  the    compensator   "i  think"

  CORRECTION The series element comprises a 1.0 Mohm and 47pF in
  parallel, not as I wrote. I wrote that at work and was interrupted
  by about a dozen telephone queries as I wrote.

  It is thus:
  47pF

  |---/&#92;/&#92;/&#92;---| | &#92; input
  1M | / circuit

  Sorry for the error.

maybe  you  can  find  some  cheap  chinese  10x  probes  that  wili  compensate  to  a  50  pf  input
maybe  deane  kidd  has  some  older  tek  probes  that  have  that  much  range
you  might  be  able  to  build  a  simple   10  x  probe   that  would  be  good  up  to  5  or  10  mhz
"heathkit  sold  probe  kits  for  their  early  scopes like  that"

  Greetings,

  My thanks to all for the very instructive replies. At the moment SC501's are my immediate concern. I wonder if it might be reasonable to just use 47pf mica cap as the SC501 adjustment instructions call for 47pf with 1 megohm. Surface mount parts would be neat.

  I will build another with the trimmer for my other scopes. I have some Le Croy 9400's that have such a high input capacity(50pf) that none of my newer probes work with them. Newer probes like the lecroy PP001 and PP002 cause a display with severe leading edge roll-off.

I am certain that a 47pF Silver Mica capacitor would do, I think
that the effort of making a surface mount version would be
overkill, just string the components across a BNC male/female pair
in a small screened box and that will do.

These boxes were available in a wide range of capacitances and
were used to 'standardize' the input capacitance to enable probes
to be switched between 'scopes (of the same input capacitance).

Geoff



Tek just uses an off the shelf ITT Pomona cast box, roughly 1" x 1" x
2",  with M and F chassis mount BNCs on the ends and wired the R & C
from center conductor to center conductor. Trivial.

About 3 months ago, I downloaded the Beta Version of IE7 from the

websites, I decided to fall back to the IE6 release. BIG MISTAKE! 
The uninstall program for the Beta IE7 left my computer in an 
unbootable condition. I had to go through great pains to get rid of 
the various IE7-related files on the computer and get everything 
working as before. Now, I'm a little apprehensive about upgrading
