Hello Job, If you end up having to repair that attenuator you may want to watch this youtube video produced by Shariar at thesignalpath.com.? He was troubleshooting an E4433B signal generator earlier

Good luck! -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Thanks for the offer Dave. Hopefully my offer will be accepted.

It's not tough at all. You'll need one cable with 50-pin AMP Champ series connectors (what people who don't bother to learn call "centronics" or "SCSI" connectors), and if memory serves a DE9 cable, I

I am considering purchasing a used HP 4195A network spectrum analyzer that has both the display and measurement units but is missing the cables to connect them. How difficult is it to source or find

Hello all, Just joined the list as I have a HP8753E to repair. It seems the step attenuator in the Source is faulty in the higher regions (region 4 and lower, attenuation above -40 dBm). While

Ok, here comes the? "A7 Pulse Generator Check"-part. The spectrum analyzer screen dump looks like the service manual, picture A7_comb. I do not have the equipment to verify the comb pattern in the

Hi all, this is kind of a continuation of the thread I started with EPROM upgrade and corrupt EEPROM issues ( /g/HP-Agilent-Keysight-equipment/topic/49147578 ). First parts of this

Hello, finish scanning them in peace, please. We just took in another 55 litres of drink, the bedroom is flooded again. I left a few pages at home at the time, to save shipping fees when sending from

I was looking at that again last night as a matter of fact send me you mailing address again where you want it mailed . I will also send what I have scanned even though it is missing pages Dave

Hello Dave, sorry to post this publicly, but I really need this resolved. Do you have any news re the Systron Donner manual I sent more than a year ago. My wife wants to finally start repairing

I’ve read that in some metrics, an HP3456A is slightly superior to the 3457A in practice, even if the 3457A might be a little nicer on paper. This isn’t limited to the much improved LED display;

Highly recommend ABBYY Fine Reader Pro(commercial $199) and/or their cloud service offering($30/month for 500 pages) that couldn't be easier to use. You pay per $0.06 page. I've used for both personal

I think you are old enough to remember that typewriters, by design, used the "l" as the number "1"... certainly all manual typewriters, and most (all?) early non IBM electric typewriters... Even the

Aparently humans are almost as prone to this. I don't know how many HP410B VTVMs I've seen advertised as an HP4108. Thanks, Barry - N4BUQ
