Looking for a replacement general purpose oscilloscope for home use

It's missing a few things, like quad or dual display modes but all in all, very nice.

Well, if you have multiple scopes, you have multiple display mode. 😉

I plugged the crappy Arb into the scope and tried the Bode plot.  The scope controls the Arb so the poor encoder interface is a non-issue.   Even with a limited number of data points, it's very slow.  Still, pretty fun to play with.

What models are you looking at?

[joeqsmith]

3000 series.   Amazed how well that Arb played with the scope.   Also, just how user friendly everything is.   I am now taking the time to read the manual.   

I think for home use, I want that 7000.

3000 series.

A good choice...

This would give you the multi-window you know from Lecroy again.

7k is next level and some.

Had a first short play with one at HQ recently and snapped it next to a 3k on the right.

Really, I want the large screen of the 7000 and some of it's features but don't want to pay for the higher BW.  It's not fast enough to let me toss my old WM and it's overkill for replacing the WR.  The daily driver has been reliable after the board swap which alleviated the need to replace it in short order. 

Talking with LeCroy about the parts scope, it too had failed the same way and had been in for service.  LeCroy swapped the board.  It must have been a common problem.  Good to have mine working again as I really like that old scope.  But damn, that Siglent will eat it for lunch in 90% of the cases and brings a lot more to the table.  They are doing things with the firmware that I would normally have written custom software for.  It's very impressive.

if you need a sds7000 for home use, what do you use for work

From the thread title, I understand you've not intended to replace your WM anyway. Just out of curiosity: what speed (bandwidth, sample rate) would be fast enough?

On the same page here, had 10" displays for some years but always wanted something bigger despite well knowing  the webserver can port to whatever display size the PC has.

Jumped up to the 12" display SDS6204A shortly after release and while it's big enough it's no comparison to the 15" 7k now having sat in front of one.

Correct, I plan to keep the WM. 

From the very first post that outlined my requirements and wants:

Analog Bandwidth @ 50ohms   300     500                      MHz
Single shot sample rate
All channels active         2G      5G                       sps
Half channels                       10G

In actual fact I've asked for the speed of your WM - and at the same time tried to make clear that it is just out of curiosity and I'm aware that you don't plan to replace it...

Half channels                       10G

With regard to this, I don't think you will easily find a 5-times oversamplong in modern DSOs anymore. A 500 MHz DSO with 10 GSa/s half channel sample rate would have to be a massively artificially bandwidth limited version of an upper midrange instrument, where the top model still has the usual 1.5-times oversampling, i.e. 2 GHz bandwidth.

The WM8500A is 5GHz BW, 20Gs.  It's close to 20 years old now, but the manuals and datasheets are still available on-line if you would like more details.
