In Related News: Ifni save me...
I put in a offer... the guy "countered" by reducing listing to a price that split the difference. Bastard has played this game before... :-DD
But... it came in under a c-note all told; so I just hope his positive feedback reflects well-packed merch.
Oh, and Vince... "Agilent - Yuckyputz!" my scaly dwagon arse!

Wow, congratulations Dragon ! :-+ :D
At that price it's basically free, amazing how the seller was dumb enough to price it this low, never mind accept an offer on it ?! :o
So that means I was wrong... Ebay is not 100% filled with "professionals" trying to screw you. Even on Ebay, even in 2022...you can still find crazy good deals !
Hmmm.... that means I must now start checking Ebay every day rather than just my local leboncoin.fr website.... OK OK....
Good deal on that one indeed. Had a quick look on Ebay US and these Agilent MSOs cost hundreds even in bad shape with broken bits and ugly yellowed plastics.
Yours looks like it's brand new, nothing missing or broken or yellowed... looks quite nice, I admit ! :-+
Plus the good thing is, the knobs are so ugly that 3D printed ones would actually look BETTER than the originals ! :-DD
So you would be forgiven for 3DP-ing a new set of knobs ! ...
Has a cool floppy drive as well ! 8)
Can't wait for the unboxing and tear down.... will it come with a module at the back, which one, and if none... are your older HP modules compatible with this more modern incarnation of the scope.
Need to find a cable and grabbers for the LA now...
I notice on all the pics I see of these Agilent face-lifted HP scopes, that the CRT looks like it uses a different phosphor ? They always look a lighter shade of green I find, or it's just me ?! :-//
There is a trend here.... who's next going to buy on of these old MSO's ?!

LOL... no, he didn't take an offer; I made an offer on the scope at its regular price and rather than counteroffer, he changed the BIN price to a point halfway between my offer and his original price. Like I said; guy's played this game before. Very shrewd.
This one came in just under a c-note all-included; the one you passed on would've been equivalent to ~USD$60, and was working and complete. This one is missing the handle and doesn't work. So... yeah. I'd have still taken that one first, even if it were a little ugly.
Expansion module on the back is not compatible; but this model has all the maths functions, RS-232 and Parallel Printer port built-in. The only optional module for these appears to be GPIB. Looking at the manual real quick, 54621D comes with built-in triggering on:
Edge (slope)
Pulse width (glitch)
Pattern
Duration
CAN
I2C
Local Interconnect Network
Sequence
SPI
TV
USB
But from what I'm reading, this is not nearly as sophisticated as the "decode" software we've become accustomed to with modern boxes, even that in my Hantek 6022BE and 1054Zed. There is another expansion module, which comes as a special set of PODs... this allows rudimentary "Decode" functionality, but only for CAN data type.
Floppy disk is pretty much a "meh" to me, as I'd probably plug into the RS-232 to transfer files. :-//
Looking at the Service Manual, while it does appear to be generally the same modular construction as my older 546xxx family, the PSU is different and the display has 32-shade greyscale, which I don't believe the monitor in those older models has. So where the 54600A is full of spares for my existing scope, this 54621D is a completely new animal. I can probably use the handle and cord off the 54600A and that's all. :-DD
Point being... even at a $97 buy, I still see it as a worthwhile gamble. Plus lots of tinkery fun.

That's the point I just made... probe colours has nothing to do with the screen. Being able to change the screen colours is useful in its own right, has nothing to do with freaking probes, hence why it was implemented in the old TDS scopes where they recognized that basic, obvious fact.
Soon car makers will offer their cars in only one colour, the colour of your house, so that the two match. What if the owner wants a different colour ? No, your house is white, I will only sell you your car in white. Model T tried that with black IIRC, but somehow, go figure, over time people really wanted other colours, strange...
I am trying to decide if I should keep my BC307 and BC368 trannystors...
--- End quote ---
I'll have any colour as long as it's black :-DD
As for the BC307 and BC368, best to think about it in this way:
TUN and TUP. Transistor Universal NPN and Transistor Universal PNP:
https://www.mikroe.com/ebooks/components-of-electronic-devices/tun-and-tup
Or just do what I did which was throw them all away by accident and just buy a shit ton of 2n3904, 2n3906, pn2222a, bd139 and bd140 and be done with it (that's 90% coverage of all normal electronics requirements)
--- End quote ---
Yeah I knew you would say that ! :-DD
I am leaning towards an intermediary solution... all these transistors I did not pay for, they are just there, so it's a bit of a waste to throw hundreds of them.
So what I am doing now is throw away those that I have just one or two or three of, because rearranging my drawers is a lot work just to insert a couple transistors. So i am going to endure the pain and take the time, I am not, anymore, going to do it for each and every tiny transistor I have... waste of precious drawers and real estate.
So ouf othe hundreds of TO92 transistors I sorted today from that bag I posted last night.... I am keeping only those that
- I already had in stock hence I can just add to an existing drawers, zero work involved
- There are many of, and their spec is something I don't have yet.
But those with inferior specs than what I have, or similar specs but too few of them... I scrapped them.
Doing that, I now have only 3 new transistors to add to my inventory, instead of 2 dozens..... that's much more manageable.
The thing is too, is that I do like to keep some old models since I seem to like older TE, and it's just cool when I need to replace an old transistor and look in my drawer and... YEAH, I have the exact same one !! :D Like just the other day when I fixed that Matra Missile 400HZ 3 phase inverter and I needed to replace a 2N1711 NPN, and I happened to have some in stock ! :D
Longer term, I think my compromise will evolve one step further. For example I think that to make best use of my drawers, I will keep only a very few TUN TUP and keep my older and more numerous transistors, but simply put them in small plastic zip bags and stuff them all in a box. This way I can still find them if I ever need them for an old TE, but they take very little space and don't waste precious drawer real estate.
Sounds like the best compromise in my particular case.
Unlike you I just can't get myself to throw stuff away, never mind TE ! :scared:

That sold before I even saw your post earlier, otherwise I'd have jumped on it myself!

Yep was considering it myself but I’m all over the place for the next two weeks. I’d have kept the power supply and sold the scope though :-DD

If it crops up again you can use me as poste restante if you want to. It's not too bad a drive from yours to mine as long as you do it during relatively quiet times.

I wouldn't throw them out if I had them. The throwing out was accidental but refreshing. I had about 10,000 transistors at one point but sold most of them on ebay and turned them into curry and then into poop :-DD
Best thing is split them into application categories and just chuck them in a drawer together. Most of the characteristics are close enough that they are interchangeable.
- TUN
- TUP
- mid power NPN
- mid power PNP
- high power NPN
- high power PNP
- RF
- high voltage
- everything else out of line, bag it up by part number.
If you note in the picture provided below, as an example, all my electrolytic capacitors are just chucked in a tub and I will pick close enough ones out and be done with it. There are so few close tolerance parts or exact values required :-//

Appreciated :-+
Hopefully a relatively smooth transition although I have to admit that letting agents are absolute sacks of shit at the moment so this is difficult. Argh >:(
