Hi all. A bit off the HP theme, however need some help. I have a Time
63132 rf (active) mixer. It also has an alt. part number of DXM602. The
LO and RF appear to be in the 10-20GHz range. If anyone has, or can
direct me to where I can find specs. on this unit, I would really
appreciate it.

Re: deskjet 895 cxi printer
One stock fault in HP printers is the print head slide bar becoming sticky. That's the chrome rod about 1/4" dia that running across the printer. Try wiping it clean with a tissue, that usually clears the fault. It shows up as all kinds of errors.

I forgot to mention that it was only a real problem because it was quite low over the bench and the cables to the lights wound around the back and side of the bench, plus they were the old inductor type ballast and the large metal housing might not have been well grounded. When a 20v max mosfet gate regularly gets 27v at 50hz it doesnt last long but all other ICs were ok, a drop in the mat resistor to 100k didnt upset any other handling and dropped the field voltage from 27 to around 2.5 I will take a look at 3M and other mats, both for the floor and the
bench top. Ah - I just checked my post, the '3m' later on referred to a 3 metre area of transition (miniumu) from an unsafe to the fully safe area. For me this did not need a 3M mat just an ordinary wool/cotton carpet which was treated with the same chemical women use when ironing to stop their dresses sticking to their panty hoses - it was *much* cheaper than the 3M or any other chemicals, I actually still have a Bokhara Afghan rug, cost about $600 in the olde days when these were being sold as "investments", still in one piece must have had it for over 20years now, more utilitarian than worth hanging on the wall for a seance ;) From what I recall, the chemical is just some ionic salt, perhaps even MgSO4 or maybe some mix which was very slightly hygroscopic, or at least had some lower resistance when dry at low humidity levels cant recall exactly. I dont use it anymore as my smallest lab is for my use only and if I ever have any very badly static sensitive devices on that 3M bench then my whole demeanor changes dramatically :P Cheers Mike 73,

Good site for that type of issue is . They
sell service kits for most HP and other models, at least for Laserjets.

Re: HP mms system catalog
Hi Erik,
You can find a copy of "Modular Measurement System HP7000 Family
Catalog" at the TestMart website ( ).
At the bottom of the page, you will see a section called: "Library".
In this section. click on the link: "Original manufacturers' catalogs"
Now, in the Agilent catalog listings, about 1/3 down the page, you
will see the "Modular Measurement System HP7000 Family Catalog" link,
where you can download the document.
The website has a registration procedure, but it is very easy. Good luck!

The only solution is to follow a good protocol. I put that in place
after I
destroyed a rare double FET while repairing a 'scope. After several careless incidents with soldering irons, I started using fireproof table tops (with static mats on top). It was some kind of laboratory table-top, a mix of asbestos and resin, that was made locally when I lived in New England. I've had them for 20 years. I remember the factory cutting room was clouded with airborne asbestos and cement dust; nobody wearing masks. The safety inspectors wound have had fits... /b ____________________________________________________________________________________ Have a burning question?

have been through this a couple of times in last 20 years, That was all very interesting - particularly that a 1M-ohm mat was susceptible to fluorescent light e-m. Two points that are worth making to clarify: 1. The reason that Al foil is bad is that any static charge on a device comes out instantly - and the high peak current that flows (even from a few pF on the gate of a FET) is so high that thermal damage occurs. A resistive mat is essential to make sure that charge bleeds out slowly enough to prevent this. 2. It is possible to subtly damage devices without destroying them totally - leading to change in characteristics, noise and/or lifetime. The only solution is to follow a good protocol. I put that in place after I destroyed a rare double FET while repairing a 'scope. Craig

FREE Equipment in WA State (Kent)
Fellow Techies,
I've said it on my web site, and I'll say it here: Scrounging is not so much ongoing acquisition as it is a 'flow-thru' of goodies. Any tech-scrounger will eventually hit the point where they Just Need To Move Stuff Out.
Such is the case with me right now, so I'd like to take a moment here to feed back to the same 'techie food chain' that I've benefited from for so many moons.
Specifically: I've got the following FREEBIES available for PICKUP ONLY, NO SHIPPING in Kent, Washington (southeast of Seattle). The only condition I place on the stuff is that whoever takes it needs to be taking it to USE IT, not to sell it for scrap.
--HP DraftMaster SX Plus large-format pen plotter, in excellent condition. Includes a whole slew of pens (condition unknown, but they've been kept capped in an indoor environment) and two packages of big paper (including a pack of Size D sheets). This item is not that heavy, and it is on wheels, but it is bulky and tall. You will need at least a small pickup truck with an open bed to move it properly.
--Compaq ProLiant 6500 server with twin Pentium Pro 200's. This was the box that was originally running my FTP archive (I've since upgraded to a later model of ProLiant). Working condition, 512MB RAM, and I think I could find a pair of rack slides and maybe even enough 4 gig drives to make a small array if you twist my arm enough.
--A pair of Sun SPARC-10 systems with at least 50MHz HyperSPARC CPU modules installed. These used to run part of my Internet presence before I upgraded to HP NetServers, so I know they work. RAM and hard drives included (though I will need to wipe the drives before they're taken as they still contain security-sensitive data).
If you'd like any or all of the goodies (hopefully all in one swell foop?), just drop me a line. If, for whatever reason, your E-mail bounces you can give me a buzz on 253-639-2996.
Thanks in advance for helping me find this stuff a good home.

Re: OT fluke 8060A battery eliminator
Thanks for the responses and advice guys.
Upon closer inspection, the writing on the meter does say A81. Thanks for that clarification.
I thought that isolation might be an issue with the run-of-the-mill wall warts.
I'll most likely use an on-hand wall wart for lower voltage measurements, which is what I use the meter for mostly when it's on my workbench. Over the past few years I've often forgotten to turn it off and end up using enough 9V batteries to make it worthwhile to consider powering it from AC.
Wonder what size or type of plug fits the battery eliminator jack on the meter?
Thanks again!

Steve,
I understand the situation.
In the hand held meters like the 8060A the battery eliminator jack is connected to -ve input terminal. This means that whatever you connect the input terminals on the meter appears can appear on eliminator jack.
In the bench meters such as the 8050A, the transformers were potted and have an isolation voltage of 4kV.
I suspect that the fluke eliminator was of similar construction, probably heavier than normal insulation on the leads and a molded plug.
The manual for the 8060A is available for free from www.fluke.com
IF you are measuring low voltage, less than 50V you can use any wall mart with the right voltage and polarity.
If you are above 50V use the battery.
I would also recommend the fluke 8050A for bench use. Very good value on eBay. Make sure that you get one with a good LCD.
I hope this helps.
Regards,
John VE3XRY

Hi John,
Thanks for the help.
I have a Fluke 8060A multimeter that I'd like to power with external DC when I'm using it on my workbench.
The instrument has a jack with the following text printed next to it: BATTERY ELIMINATOR JACK CAUTION OPERATIONAL HAZARD EXISTS IF BATTERY ELIMINATOR OTHER THAN FLUKE ASI IS USED.
Or maybe that's AS1.
Did Fluke make that model of battery eliminator? I don't find it on eBay.
What would be the "operational hazard" if I powered the meter from a wall wart? What size/type plug does it take and how should I wire it?
Thanks.

Re: Need logging help with hp 5328a
James,
The TCL scripting language has good support for GPIB. It is pretty easy to
write a script in TCL that reads the 5328A once every so often and writes
the result to a text file. The text file can then be read by Excel for
further processing.

Need logging help with hp 5328a
Hi James:
Spark Fun has the GPIB-USB Controller.
In addition to the EZ GPIB software there's also a "Plotter" program at:
that's designed to process time interval data (like you would measure with the HP 5328) and from that get Allan plots.
Note for high stability work you don't have time to make frequency measurements and instead make Time Interval measurements, typically comparing a GPS timing receiver's 1 PPS with a 1 PPS derived from you oscillator.
You might also consider joining the Time Nuts mailing list
Have Fun,
