Re: Fake fire New
Dan, I certainly agree that this is not the forum in any sense for a political debate.? Unfortunately you went on to engage in exactly that.? "The Media" has destroyed its own worthiness and doesn't need anyone's help. George On Sunday, October 15, 2017 7:16 AM, "Dan Nelson blaze_1024@... [hp_agilent_equipment]" wrote:

Re: HP 8341A sucessfully FIXED!
Wow. Nice work, Tobias. Sometimes we learn the most when things seem hopeless. Your reasoning was right that there was nothing to lose by taking a chance on opening the YTO, and you came up with a great alternative to get around the problem.
I hope you plan to keep that web-page available - it's a good story and resource with good pix of the YTO innards, for future reference. I'd recommend you also post the images to the photos department here. Ed |
Re: Fake fire New
开云体育Greetings,I have been reading some of the posts regrading the inaccurate reporting regarding the Keysight plant in Santa Rosa.
While I find inaccurate reporting as disturbing as most of us, I must also note that I am growing weary of this ongoing discussion.
I am taking the time to add to this conversation to suggest our efforts and energies might be put to better use if we can discover how we might help Keysight employees who have suffered loss as a result of these fires.
I know of at least one Keysight family who lost their home and possessions.
While it is reasonable to believe that most of the material losses will be covered by insurance there is, without question emotional loss and perhaps we can send some simple, yet supportive and encouraging gifts, to the Keysight campus for those
that suffered losses.
Regards,
Ken

HP 8341A sucessfully FIXED!
开云体育Hi all,
probably some of you have seen that I had some problems with a 8341A. It was indeed the YTO which failed! But, I was incredibly lucky to fix the YTO. I also did a front panel RF output retrofit on my machine. Some pics of the YTO and stuff can be found on my page, if someone is interested :-) Now I can proceed to my next project, a 5342A frequency counter (hopefully not a blown sampler) and a 8568B spectrum analyzer with blurry focus on the graticule. Best Tobias, HB9FSX |

Restoring HP 1740A scope, strange waveforms seen, assistance please?
Hi all, I've been a member for a while but lurking in the background while working on the scope and looking out for any discussions about a 1740A taking place. I now have the scope in a running condition after replacing 2 faulty transistors and now while testing the scope with the 1V test connection I discover that channel B works as expected but channel A works OK up to 0.2V on the volts/div switch, moving to 0.5V and upwards the trace goes odd.? I was wondering if anyone could point me to the area that I need to be looking at on channel A to cure the problem. I have uploaded photos of? both channels with the settings on 0.5V and 1V so you can see the problem?

Re: Fake fire New
Please please keep politics and conspiracy theory rhetoric away from this group.
If I want rants and abusive postings, I can find gobs of them on sci.electronics.design, surrounding a few technical gems. At least one of the (other) contributors to this thread can be found "over there". Although it isn't directly relevant to this group, one of the good things about working at HP was that any such statements would have been quickly and effectively stamped on. That contributed to a pleasant working atmosphere. |
Re: Fake fire New
I have friends in the areas affected by the fires that I haven't been able to contact. I am praying for them, and the others who are affected.

Re: Fake fire New
It was a commercial TV station. We pay for it, whenever we buy something sold by their sponsors. They are supposed to be professionals, not some hack, with a free blog. They just make things up, rather than actually do their job of investigating the news before reporting it. I worked as a Broadcast Engineer and radio & TV stations. Shoddy work like this, is the main reason that I left that field. If I did my job as poorly as the 'News' the stations would be off the air more than they were on.

Re: Fake fire New
This is not the time to have this type of discussion. Many of us either visited, worked there, and for my part at least, have gotten to know many people in Santa Rosa. Most are retired now and I think we should all be praying
they are all well. Regards Bill Lauchlan From: hp_agilent_equipment@... [mailto:hp_agilent_equipment@...] Sent: Saturday, October 14, 2017 10:14 PM To: hp_agilent_equipment@...

Re: 3585B Spectrum Analyzer
If it ran then failed after a little time I would tend to suspect a tantalum capacitor is shorted or shorting.? Keep that in mind when troubleshooting.? The guide might get you to the proper area then look carefully for burned caps or other components before digging in super deeply.

Re: Fake fire New
It's not like it was, 50 years ago when it would have taken 20 minutes (at most) to find out who the company is. Now a few seconds with a search engine would have told them who Keysight is. The difference between losing two portables and a couple vehicles vs losing the entire corporation is a huge error that a real journalist wouldn't have made.

All, ? I have a probe for the Boonton 91 just about free for the asking. It is a model 91-3C (electrical condition unknown - if you know how to test, tell me and I'll do it) with no screw-on tips and with a section of the cable taped for a few inches; it was probably attacked by a rogue soldering iron back in the day. It might fit in a padded envelope or it might have to go small flat-rate. Let me know if you're interested. ? geo

Re: Fake fire New
?Whats with the "Fake News" rhetoric. Using the term "Fake News" infers purposeful?deception which I highly doubt is the case. Reporters are humans and they do make mistakes. Also, not everyone?is an electronics nerd interested in $100,000 pieces?of test gear so It's not surprising that a normal person wouldn't know who Keysight is. How many electronics geeks?know who Beneteau is ??and yet they are worlds most highly regarded?builders of high-performance cruising and racing sailboats. By the way, a quick check if the USGS shows that there was indeed a small earthquake just outside Sonoma on the 14th.? ?? |

The calibration error codes are listed in service manual volume 3, page 11-15. May be ROM Checksum Error but follow recommended procedure in manual for your particular observations.

Subject: [hp_agilent_equipment] 3585B Spectrum Analyzer To: hp_agilent_equipment@... Date: Saturday, October 14, 2017, 3:40 PM I was fortunate enough to receive the 3585b SA recently. When I first picked it up it powered up fine and display appeared to be normal.? Getting it home and after setting it up, it again worked fine. I ran some tests and looked at signals on the screen and was happy with what I was seeing. However powering it up a couple of days later, there is no display other than a dot in the centre that flashes. While booting up, 1st heard is one beep followed shortly by 2 and then a long pause before several beeps are heard, about? 28.? They start off quickly and then slow down near the end. I've re-seated some boards and several connections with no change in results. Any help in pointing me in next steps would be most appreciated. thanks, Peter ve3poa |
