content: Hi everyone,I am trying to make a power supply for my Agilent active probe for spectrum analyzers:http://www.home.agilent.com/en/pd-1000001990%3Aepsg%3Apro-pn-85024A/high-frequency-probe-300-khz-to-3-ghzThe problem is that it has a power connector (female) with three pins. On the side of the spectrum analyzer there is a male version of this connector. For the life of me I can't find what type of connector it is so I can purchase one. If anyone knows, I would appreciate it. I have used this probe before in one of my videos with the Rigol DSA.Cheers,

content: It looks like a Neutrik D-series XLR connector, does it have a locking mechanism?I'm going by the users manual connector picture(not very helpfull), can you provide a picture?

content: Page 7-6 has the voltageshttp://cp.literature.agilent.com/litweb/pdf/85024-90031.pdfThere is a Power Probe Connector to Banana Plug part number 85024A-001http://www.transcat.com/catalog/productdetail.aspx?itemnum=85024A-001$164.00This link shows a picture (included below) of the adapter that includes the connector (but it doesn't really show it)http://www.home.agilent.com/agilent/editorial.jspx?cc=US&lc=eng&ckey=1731516&nid=-11143.0.00&id=1731516alternate part number 87405-20012 (5X5 part number)http://www.metrictest.com/product_info.jsp?mfgmdl=HP%2087405-20012(D)$ 266 refurbishedThey recommend using Agilent E3620A, E3630A or the E3631A, DC Power Supply for the adapter to power the probe.but I can't find the datasheet to get the actual connector.---- now reaching a bit because they might share the connector with HP probes-----page 2-3 of this doc seems to have the same connector but the HP probes came with the power already attached.http://cp.literature.agilent.com/litweb/pdf/41800-90010.pdfhttp://www.home.agilent.com/upload/cmc_upload/All/EPSG087227.pdf?&cc=US&lc=engMost promising connector picture here (2nd image attached).

content: I mean on the first document I linked:http://cp.literature.agilent.com/litweb/pdf/85024-90031.pdfIt describes the power connector body to be part number 5060-0466 and the connector sleeve to be part number 5040-0494 but they should be already on the probe and hopefully it reaches the connector on the side.Otherwise the connector body cost $45 for the female and cyr posted the link to the male one.http://www.home.agilent.com/myagilent/faces/partDetail.jspx?partNumber=5060-0466&imageStatus=YESThe connector sleeve costs $139!!!!http://www.home.agilent.com/myagilent/faces/partDetail.jspx?partNumber=5040-0494&imageStatus=YESI'm attaching the image of the female body connector (the one that costs $45) part number 5060-0466Again, the base of the probe shows the power cable that might reach your connector.The banana adapter is for external power but should have the same connector.But since you want to make a power supply for it, I would go with the part that cyr posted or buy the banana plug adapter linked on the previous post for more ($164.00)Also available fromparts.agilent.comfor $316.00!!!!http://www.home.agilent.com/myagilent/faces/partDetail.jspx?partNumber=87405-20012&imageStatus=YES

content: Thank you everyone, much appreciated.They charge so much for a such simple cheap connector. I am tempted to just craft one out of plastic by hand. Or mold one using the male connector and some epoxy.

content: that is a custom connector made for HP. buy it from hp or , get a probe power supply box of ebay for 50$ and scavenge the connectors from there.if youneed the cable part you are shit out of luck. you can only hope to find a broken probe and salvage the cable from that.

content: Quote from: Hugoneus on March 29, 2014, 04:48:35 pmThe price point probably has to do more with being obsolete than the manufacturing cost at this time. And as time passes they will ramp up the price just to compensate for the storage cost and low production runs.Then again, a 3D printer might do the job.And just noticing who you are, you could use your connections (pun intended) to get the banana power adapter 85024A-001 or 87405-20012@free_electron, HP has been Agilent for quite a while. And you probably already know that

content: HiI am aware of this thread been "silent" for more than 2 years but I was unsure if a new topic would be better instead of posting here about this good info I have found out on this connector issue.I discovered that the same connector that is on the spectrum analyzers where you connect the HP 85024A HF probe too also exists in the probe power supply HP 1122A. I found out that the part number for that internal connector in these power supplies is 08711-60037 and when searching around for that part I was lucky enough to find an eBay seller selling two of those connectors for 17 USD each!So if you are in the search for this special connector you might either try to find this connector 08711-60037 or find a broken HP 1122A (or similar) probe power supply from where you can pull out the connector.The 08711-60037 looks like this:

content: I've been looking into adding an active probe and the idea of a used 85024a and external power supply appeals.I looked into the Keysight adapter cable and the price is now over $400! See screenshot attached.If I get the probe at a reasonable price is there a reason not to just cut the power connector off and add my own bananas? (I've got an R&S RTB so I won't be using with HP/Agilent/Keysight scope anytime soon.

content: Wow, at that price I would make my own connector using three machine-screw female pins and some moldable plastic likehttps://sugru.com/

content: Yes, needless to say that option is off the table!I'm happy to cut the power cable on the probe and terminate with bananas for a bench supply. Is there some technical reason that people don't know this? Bar respect for a nice probe…Cheers,Ruairi

content: Has anyone ever found a source for the female connector that mates to the front panel? I have a Rigol DSA1030 that has a three pin male "probe power" port on the front that I'd like to use to power a homebrew high impedance probe. Unfortunately even Rigol doesn't know the specs for the connector (couldn't believe they didn't have the part/port documented somehow)...it appears that it may be a "Lemo" brand connector of some kind.
