I only have a 2430, but ISTR the main difference between the two is that
the 2430A has automated measurements, whereas the 2430 only has cursor
measurements. The two are not the same, and at the very least the 2430A
would be a couple of years younger than the 2430. If this was an eBay
purchase, I’d say you have a good case for claiming item not as described.

Hi,

Yes, they are different. The 2430A is more in line with the 2432 and 2440.
The 2430 (not A) even has a different front panel. Check right below the
horizontal speed knob, the A version has more buttons there. The sample
rate and the bandwidth are same for the 2430 and the 2430A, but there are
some functions related to automated measurements and measurement automation
are missing.
So whether this is an oversight on the side of the seller or deliberate
scam, I don't know, but you should definitely complain. Check the photos
and the description as with the different front panel, it is easy to tell
the difference.

Start by comparing the one you got to the one in the auction photo.

well,the seller admits it was listed wrong,so i have a case with ebay to return it if needed for a refund,but decided to keep it if i can fix it,heres part of what i posted on eevblog: hi all i just got this scope with a bad nvram backup battery showing a fpp 4000 fail,ive now replaced the battery and get the following fails during the startup self test:6000 cksum-nvram* fail,any idea how to fix this?or what the cause is,i actualy used an 18650 sell at 4v in place of the original battery,so 4v not 3.6,i did connect the battery before removing the old one but had a wire come off so the nvram cal data would of got lost,is this just a matter of a recal?,if so how do i do it?,tia m3vuv.

Hey Quadzilla,

There is most likely nothing wrong with your scope, but you might try a few
things in order to get better help here - or anywhere.

1. Answer the questions posters here ask you.
2. Outline what you've tried, what worked and what didn't, what results did
you get.
3. Don't ignore the advice you get.

So, do you have a service manual? Have you read it? Have you read any of
the 2430/2430A repair threads here or on EEVBlog?

To get my 2430 to a clean non-faulting state after repairs and battery
replacement, I had to COLD START it a couple of times.I forget whether you
need to set the calibration switch or jumper to enable that menu.
Have you tried that?

Note that you've been advised against using anything but the original
battery in this scope. This is because anytime the battery dies, you'll
lose calibration and you'll get 6-9000 errors up the wazoo. It's fine to
plug in whatever to see whether there are other problems, but the original
battery is designed to last decades in this circuit, and anything but a
suitable primary cell will leave you high and dry before too long.

So for gigglement I went and looked up the EEVBlog thread. Here's what OP
got: . For 70 pound sterling, I
don't think he can complain too loudly. The listing title is clearly in
error, but as clearly this is a 2430 as depicted by all images, comes with
a manual too.
The FPP submenu is depicted in the listing, and it shows BATT-STATUS. The
focus problem is probably adjustable, but the screen looks nice and bright
otherwise, so for sure fixable.

PS: OP; whether or not someone tells you how to do recal (again), you'll
have to look up the specifics in the service manual. Do you have one? Have
you looked up the calibration section?

for whatever reason,it now seems ok,all ive done is cycle it a couple of times and all self tests now pass,wierd!,can anyone explain this?as far as sending it back for a refund goes,i wont bother as for ?70 it seems a decent scope,just hate the ballach to set these up tho compaired to analog,horses for courses i suppose!,happy new year all! 73 m3vuv.

Yeah, these are a PITA to use compared to the 2400s or earlier. Slow as a
wet week too. Because of the architecture, they're about as near blind a?
makes no difference. This scope spends more time digitizing the signal than
capturing or displaying it at almost any speed above where roll mode is
available. Roll mode with envelope capture is awesome, however.
