3586B Selective Voltmeter Help trouble shooting
I bought an HP3596B off EBay.
?I have a service manual on order. ?First thing I did was remove the leaky battery and thoroughly clean the PS board. It looks good, however if I look down to the edge connector inside the unit I can see it has the blue buildup on it from the battery leak. I'll save that until I disassemble to clean and lube the switches. ?At power up the self calibration comes back with CE-F. One poster suggested I put in? Recall, Decimal point, Center Frequency ,8, when I do it comes back with Fail? 1? 0. ?Anyone have info on what the error codes denote? ????????????????????????????????????? Thanks, Lamont |

DELETE THE OTHER MESSAGES FROM ME THIS MORNING
Just to be sure, I've changed the subject line.... DELETE THIS MESSAGE!!! A message purports to come from me this morning to various people and groups in my Yahoo mail list.? It is NOT from me.? Delete it.? ?Do not click on the link in the message - it probably takes you to a bad place.? Just delete the message. I don't think my Yahoo account has been compromised.? My e-mail address was probably just spoofed, but it's an interesting random-seeming collection of e-mails from the few I contact through yahoo mail. ?Sorry for the inconvenience, ? Dan

Re: 8568B YTO unlocked
Tobias,
Look at page 9-49 in the 8568 service manual (Vol. 4). The section is called "RF Section Analog Troubleshooting". The problem you describe does not seem to me like it's YTO related. It sounds more like spinning? the rotary pulse generator somehow corrupts the tuning ramp. Vladan |

Re: Found a on line auction selling several HP items Oct 26 end date
I have had a UPS store pack for me only once; the store, in suburban Minneapolis, did an excellent job with a large tube-type oscilloscope, getting it to me undamaged. Packaging and shipping to the west coast was ~$100 so definitely not cheap. Jeremy

Re: YIG pinout
开云体育Hi DaveAs far as I have learned, most HP YIGs are pretty similar.
Have a look at the picture here
https://hb9fsx.ch/wordpress/wp-content/uploads/2017/10/20171011_095836.jpg
where you can see a YIG osc with its bias board, A44. There are some pin numbers.

Re: Found a on line auction selling several HP items Oct 26 end date
LOL.. I was not trying to endorse anyone one. ?I have had good luck getting equipment from on line auctions. ?Some on this board, may be close enough to not needing anything shipped. ?
This auction has potential since the primary focus is HAM stuff. ?Someone may find the a deal. |

On my 8566b, if the span is greater than certain MHz, the sweep source is operate in “Lock and Roll” mode - locks to the sweep start frequency then applies a ramp to roll.

Re: 8568B YTO unlocked
开云体育Hi,I have the manual, of course :-)
But I cannot find some info about when the YTO is allowed to be unlocked.
I also have not yet managed to fix the flickering trace. Actually, 'flickering' ist not quite the right expression; it is a bit more complicated: if there is a signal on the screen and the marker is moved along the trace, the trace is slightly 'pulled'
along the frequency axis towards the direction in which the marker is moved, which looks like an unstable, flickering display if the marker is moved fast (e.g. when turning the knob rapidly). As soon as marker movement is stopped, the trace bumps back at its
former position.
However, this absolutely strange behaviour can only be observed when the span is wider than 1 MHz; in this case also the YTO unlock LED is flashing (but no warning message on the screen).
I hope I have some time tomorrow to check the tant caps. I hope it is not the YTO or a mixer which went on the blink, but I guess as long as the YTO oscillates and signals can be viewed correctly (in principle) on the screen, then the RF path seems to
be all good.

I don't know about the screen flickering, but I do think the YTO loop behavior is normal. At wider spans it is not constantly phase-locked - it is driven open-loop with fairly accurate sweep current, and I think possibly re-phase-locked just at the beginning
of the sweep each time around. For wide spans, you can't resolve the small frequency error on-screen anyway, but for narrow ones, more stability is needed, so the LO is locked. It's also possible that the narrow spans instead fix the first LO and use the second
LO for sweeping - I can't recall for sure, but it should be one of those two schemes. |

Re: Fake fire New
Richard Solomon
开云体育I am sorry, but just saying ..."poor or lazy reporting"... is only sugar coating the facts.
The fact is, the reporter did not confirm his story, so in fact, he (she or it) made up
some of the alleged facts.
If you make up facts, that to me, is FAKE.

Same experience. Shipped an 83712 from NY to CA. Had them pack it. Glad I insured it. Face plate smashed in.? Pictures of it on the counter @ the UPS store will make the claim easier.?

FS: HP Jornada palmtop computers
Hello--
I'm offering the following HP small (palmtop) computers and accessories. One HP Jornada 720 with one expansion base: Includes stylus and original battery (needs replacement). This unit boots when connected to an external power source. Two HP Jornadas 820 (F1260A): both include original batteries: one has a broken right-side screen hinge, the other is mechanically intact. Both units boot when connected to an external power source. One HP 820 sync cable (untested). One HP F1265 AC adaptor (12 VDC @ 3.5A) in working order (supplies power to HP720 and HP 820. One 16 MB Compact Flash card with HP 820 user's manual and other files. I'm asking $25.00 for the lot of all items, which includes USPS Priority-mail shipment (a $13.60 "value") for shipment to U.S. locations. (These palmtops may have had test-and-measurement applications, but it's unlikely. I apologize in advance to anyone who takes umbrage at my offering these little jewels to the group.) Question welcomed, PayPal honored. 73-- Brad AA1IP |

I was looking for some Ham equipment and found a Kansas City based Online auction listing several HP Items.Sort of: "For shipping, we work with a local UPS franchise. They will pickup your items the week following the sale and contact you directly to discuss shipping options and costs, and then you will pay them directly." My experience is that UPS store packing is very expensive, but also completely ineffective at protecting the contents :( Highly disrecommended. |

Re: Request for E4406A CLIPs (was Re: E4406A Input Attenuator)

[mailto:hp_agilent_equipment@...] ? ? Just to help clarify on Alexander's request - This is a completely different repair from the one I've been working on (still not complete unfortunately) and he's just asking for the CLIPs if anyone has them. ? I only have the RF one but I think he needs the Front Panel & Power Supply ones if they exist. ? Alexander - It occurs to me now that you might not be able to get one for the power supply as a lot fo these were purchased from 3rd parties and HPAK never had the schematics to start with. ? Hope you get it fixed.
