Hi all



Looking for operator serves manual for HP 8402B



Unfortunately Dave at Artek dues not have it



Regards Paul; ~England

Calibrate no, get close probably. If you only have one head and a sig gen you REALLY trust you could run the cal procedure. It would be a good/reasonable indicator but not calibrated. You really need to do the meter with the range calibrator.

I used to have one but it lives in Eagle Point Or. with a friend of mine. If you were domestic I’d try to get and then do the cal for you.

Regards,

Hi,

Is it possible to calibrate a 431C power meter with a 8477A or do I need a 8402A for this?

Thanks.

Dave,
Sorry about that. I had Fred on the brain. I live in Reedsburg, WI near the Dells.
GOD Bless and Thanks,

Hello all,
This is an update. My insurance company has declared my car a total loss. Please help me out and help this sick old man to stay in a car by buying my 16700B and all of the accessories.
GOD Bless and Thanks,
rich!

Hello all,
I hit a deer in WY with my brand new car. They are probably going
to total it. My GAP insurance will pay off the loan but I am probably
going to be left on foot. I am getting out of working on electronics.
I have a HP 16700A LA and 16700B expansion unit for sale. There are 5
16555D cards in the 16700A. The interconnect cable for the the 16700B
is here. There are five pairs of cables for the 16555Ds. There are
terminators for the cables and clips. The HDD in the 16700A has been
upgraded to a Seagate ST 318417N and there is an external HDD and case
connected to the system for extra storage. There is also a SCSI CD-Rom
drive and a floppy drive installed in the 16700A. The latest OS has
also been installed.
It will take two very large boxes and a smaller box to packaged it
up for shipping. So shipping will be expensive. Local pick up is
welcome. It operates and all of the cards are good. I will guarantee
no DOA. Please make me a fair offer and help me out with this. I will
take Paypal F&F, Money Order, Cashiers Check, Personal Check but it
will be held until the check clears.
GOD Bless and Thanks,
rich!

  Morehead, KY?  Bet I know who that is.  He will pipe up soon I think..

 George,
 Thank you for your reply. After a total of 6 hours searching I just
 found a seller on the auction site listing Plessey Prescaler/Frequency
 divider IC's. In the description he listed theSP6806B. He stated that
 the IC's were NOS from Watkins-Johnson and he is located in Morehead
 Kentucky, United states. The price is $9.50 each IC. I ordered 2 and
 will replace the bad one in about 2 weeks.
 
 This may be the last problem for the 8656A. I will then move on to the
 stack of more than 50 pieces of test equipment. That is not counting
 about 30 Tektronix 7000 plugins.

Hal,

Congrats on joining the modulation domain!

As you know already, it’s really a sleeper. Although it works very
well for viewing any sort of frequency modulated waveform, my
personal favorite use for it is as an extremely precise counter.
There is a reason that it’s called a frequency microscope.?

FYI, adding the deep memory option is quite easy. If you search
around you’ll find instructions. All you need are 4 more SRAMs and to
move a couple of jumpers after installing them.

All:

Picked one of these, with Opt 31, a while back and... wow.? Just,
wow.? The more that I research it and play around with it the
more impressed I am with it's capabilities and usefulness.? After
reading a few other owner's experiences with it a common theme
is; "How did I miss knowing about this?? Why is it not well
known?" - very much my reaction.? I would think that if any one
group of people might be aware of it, those here would be the
ones.? But here, as elsewhere, there are very few mentions about
it.? Anyone else use one of these?? Usage tips or other information?

Just curious,

Hal

Subject: Re: [HP-Agilent-Keysight-equipment] HP 3478A Ohms Calibration

Hello to all in this group,
Thanks for being understanding during these trying times.? I have not yet returned to my office in Minnesota where the Red Devil resistors are so as you can see, I have not been able to fulfill my promise to you as I am still in Loveland, Colorado.??

I have orders in to get a Loveland cal on all of my 3458A DMMs which I was planning of have performed while in Loveland being that my office here is just 3 miles from the Keysight facility.? That does not look like it is going to happen so this will all have to wait until Keysight cal lab is back in business.? I have upgraded the CAL RAMs on my 3458A meters as well as some of the other parts related to the high stability OHMS and voltage reference internal to the meters.

The good news is that I have gone through my inventory here in Colorado and have found considerably more items than I remember having.? I have parts and boards and many case parts related to the following instruments and related I/O cards:
3421A, 3455A, 3456A, 3457A, 3458A, 3468A/B 3476B, 3478A, 3488A, 970 probe meter,? some oscilloscopes 54501, 54511 and spectrum analyzers? 3582, 3585, 8754A, 8753A? and all the I/O cards for the 3488A:? 444XX series(XX= 70, 71,72,73,77,78, 91,92?and I/O cars for the 3457A.??
I have a large supply of the Aromat relays(new unused) that I used in the design of the 4447X series of I/O cards for the 3488 should you need to replace any as well as other components used on the boards

The 3468 and 3478 meters and related axial leaded and ICs and custom hybrids I designed are also in my inventory and are in sufficient supply to fill anyone's needs. In fact, the SAFT and ETERNACELL 3.0v lithium back up battery for the cal RAM some were looking for earlier are here in Colorado.? I can make them available at a reasonable price of $2.00 each.? All of them measure 3.03v or better.

Thank you and I will notify group when I am back in Minnesota regarding the Red Devil resistors.
I can ship other parts from Colroado if needed.? I am scheduled to hit the road to Minnesota once I load up the truck with the inventory on the 28th of April.? Hard to believe I have been here almost 2 months when the initial plan was to be here 2 weeks.
