content: Hello,As I am not using it anymore i want to sell my Agilent 54622D two channel MSO.It is triggering and displaying waveforms from my signal gernerator just fine but i cannot get the probe compensation to work.I managed to fix the issue with the Probe Compensation. It was just a loose cable!The usercalibration and selftests pass without errors.The handle was broken as i bought it two years ago. i glued it back together.The backup battery was swapped by me for a battery tray to easily swap it in the future.It will come with two Agilent 10:1 Probes, a full set of Logicprobes and assecories for them.Due to its condition i will sell it a sworking but partially broken.Now it is fully working.i want 220€ (negotiable) + shipping

content: These are really good scopes with quality oozing out all over. I have one of these with latest firmware installed you get all options enabled. Good scope - way better than cheap scopes from China. Only if it had USB it would be perfect. I used serial to save images.

content: Quote from: kawal on May 14, 2020, 02:10:10 pmAgreed; I "grew up" on some of these at school, I think the same model anyway, though they were amber screen, not green(?). We used NI GPIB-USB dongles (bolted to the lab benches, as were the scopes and other gear) for comms. Have also used 54600 and 02, truly excellent line of scopes, much easier to use than contemporary Tek offerings.Tim

content: I had this scope and I remember printing to floppy and it uses green and black. The cons is that you need a PC/laptop with a floppy drive (there are USB units that work pretty well)

content: Screen captures saved to the floppy are grayscale TIFF files. If you have the latest firmware it will have the Agilent logo and "Agilent Technologies" at the top.

content: Quote from: kawal on May 14, 2020, 02:10:10 pmI have one too and agree, it is a quality item. I fitted a quieter fan, and a new backup battery...You can get an Agilent GPIB adapter to screw on the back, apparently. Not sure if that is any better than a serial cable, though...

content: Quote from: kawal on May 14, 2020, 11:05:33 pmWhat version of the Agilent I/O Libraries are you using with the Intuilink data capture 4.3 ?It asks for version 14 on install, but I see Keysight has many newer versions... I was wondering if there is any benefit to using a newer version.I've got the latest version drivers working, they see the scope, but Intuilink isn't cooperating with the new drivers...

content: The Intuilink data capture 4.3 didn't work for me (serial, Windows 7)I got annoyed and started writing my own software to query the scope, which DOES work... I'll start a separate thread on that if anything interesting comes out of it.

content: Does anyone noticed that the screen captures downloaded by RS-232 are really blur. But if they are taken by the floppy way, the picture quality are better and file size also smaller.

content: Recently bought an Agilent 54622D on Craigs List, can you please tell me which quieter fan you installed, and any issues.I love the scope - the fan noise though is too much - thanks.Commissioning my "new" 54622D included installing a leaded C123A 3V lithium cell from a broken smoke detector.The intensity knob was broken, a 3/8" length of 3/8" diameter oak dowel screwed and epoxy glued into the broken end of the control rod, covered by a nylon cap restored nice operation and decent cosmetics per picture.Upgraded the firmware to latest A.02.31, and made a PMP (Poor Man's Pod) from a 40 way computer PCB to hard drive/floppy/DVD ribbon cable. A bunch of 91k Ohmseries resistors, and a green LED powered off the 5V from the 54622D to confirm pluged in correctly. Not the greatest signal integrity, it crosstalk's onto other digital channels, but it's fine for the few MHz signals I am interested in when working on old CD players etc, hope attached pictures are of interest.

content: Quote from: PlaneSailing on March 11, 2022, 08:24:02 pmYou're probably better off asking about this in the Test Equipment sub-forum.However fwiw, any decent modern fan is probably an improvement in noise and airflow, Noctua are well known for example. Just make sure you pick one with the same voltage and physical size, should be straightforward enough.

content: I'd be interested to hear back what you find about replacement fan. It does seem quite high airflow but as AVGresponding says, I suppose a new one will be better even if the airflow is matched.

content: I won't be at the location where my scope is for a few weeks. Then, I will let you know what fan I used, so you have an example.One important modification is to rubber-mount the fan, since the original mounting allows the vibrations to be conducted into the entire chassis and enclosure...
