The RICM just received $1,000 to buy a new oscilloscope. I would like a
four channel. and color would also be nice. The bandwidth doesn't need to
be high because we usually work on ancient equipment.
What would you suggest?

Siglent or Rigol are good bang for the buck. Rigol has a four channel
one, and they are far below 1000 USD. I think Keysight made some
cheap-er scope recently too.
Or if you are in the states, get a old Tek -- you can get those really
cheap.

The Rigol scopes have the features that you're looking for in your price
range. Dave on the YT EEVBlog has spent some time on them.
There have been some notable software bugs, but Rigol seems to be pretty
diligent in eradicating them.

I have a Rigol DSO and absolutely love it. Bought it from Saelig - they offer a nice
discount to members of the EEVBLOG forum. I have seen a couple of updates since I bought
it. Look for a sale where you can get some of the add-ons thrown in at no additional
cost.

Really NEW, or just new for your museum? I got a Tek 2465
on eBay that I am quite happy with, for quite a bit less
money. There are some decent import digital scopes (such as
Rigol) that many people seem to find good.
If you are not familiar with digital scopes, there are some
gotchas there. You can't tell the trigger rate from looking
at the screen, but then they can see what happened BEFORE
the trigger event, and can freeze a single-shot event for
you to look at. The good Tek DPO scopes have not come down
enough to meet your price range (yet).

I would suggest just about any used Tektronix TDS 200mhz or higher 4
channel scope with a good display- from the mid 90s or newer.
Make sure to look up the model year to ensure it has reliable caps.
I have not been a fan of the new designed-in-china test equipment like the
'rigol'

Right now is prime time to evaluate and snag a HP Agilent 16700 with
digital scope channels and logic analyzer channels to boot. You might
be able to snag one along with a new unit. WRT to old equipment the HP
Aglient 16xxx logic analyzers are pretty much the best for every device
I've ever worked on. I don't know that the glut of really nice hardware
will last a long time.
Another thing to consider is the Saleae line of digital probes. There is
a 16 channel unit with analog capture feature now. That unit if you can
capture at a rate that your hardware can handle will capture trace till
you run out of space on the attached pc support device.
If you attach it to a signal that is serial, every channel on the logic
analyzer becomes a serial protocol analyzer, and will export ascii
serial to a file if you are doing that task, as a side benefit.
I'd budget at most 1/4 of your $1000 for that purchase if the donation
allows that.
i've got the 8 channel unit.
Beware the saleae type units may be 3 v input, be sure to check that, as
my suggestion won't be much use for that case. I've not shopped them
lately, but my older 8 channel unit is 3.3 max only, though I've used it
on 0 - 5 v
thanks

I use a RIgol DSO at work to replace a 200mhz Tek with power issues.
Far better scope.
For the money we paid, 4 channels and wide band its very decent. Being
able to get
screen grabs to a USB stick is a big plus.
I personally have a Rigol DS815T spec analyser with tracking generator
and its a good performer.
Not up to the standards of a R&S FSH6 but about 1/15th the price.

If it is your only scope I recommend an analog scope of at least 100 MHz, with dual trace
and delayed sweep.
If you already have an analog scope, I recommend a logic analyzer instead of a digital
scope.
If you already have both above, I recommend a digital scope.

We have lots of dual-trace Hitachi 25MHz analog 'scopes that were donated
by BMI. They are fine for the low speed work that typically do, and don't
have some of the interesting problems that digital 'scopes have. We can get
a deep discount on any of the 'scopes that BMI has:
https://www.bmisurplus.com/products/category/oscilloscopes.
I was looking at some of the mixed-signal 'scopes like the Rigol MSO1104Z.
Having a 'scope and a logic analyzer in the same instrument, with both
'scope and logic analyzer triggering would be very nice.

I've almost always used TEK scopes, and liked them. What ever you choose,
see if they will cut you a good deal for being a educational or non-profit.
A lot of companies will, especially on a discontinued model.

Great idea about looking for a non-profit discount. That might not work for
the Chinese 'scopes, but it could make the US 'scopes prices more
competitive.
