GW-Instek MPO-2000
nctnico:
It is also interesting for the educational market. Having one device is easier to deal with compared to a whole bunch of devices which may get stolen / lost.
But also for R&D use having a single device on your bench helps. If you run into a problem, you press a few buttons and have protocol decoding together with the signals in the analog domain. The same for FFT. Sometimes it helps to look at a signal in the frequency domain where a DSO can go near DC which most spectrum analysers can't do. I have a DSO on my bench with an internal AWG. If I need a signal, I use the AWG in the DSO first because that is always there. My signal generators are tucked away on shelves.

And what are you saying is scope + spectrum view + AWG.
Which is sometimes usefull.
But they added a PSU and multimeter, which are separate connections...
Those devices are weird combination on a scope.
Analog Discovery had PSU, but that way useful because it was so small..
I personally don't like multifunction devices. Too many compromises and if you have a malfunction, you have none of 5 devices...
nctnico:
I don't see a high added value for a DMM and PSU either but the PSU might be handy to power a circuit. Sometimes I use a front panel USB socket on an instrument for that purpose. For an educational institute having an all-in-one is easier in case of malfunction. You only need one kind of spare unit instead of 5.

I rarely use a standalone dedicated AWG since the 'scope ones have become so useful. I ended up selling a Rigol AWG it had gone into disuse since the oscilloscope one did almost everything I needed on a day-to-day basis. I still have another AWG but hardly used.
The spectrum analysis is essential in an oscilloscope to see detail that is easy to miss or hard to make sense of in the time-domain view. The newer GW Instek scopes like MPO and (slightly older MDO EX) are doing something different with their implementation to make it more usable/granular/responsive, there's some info here in the MDO 2xxx-EX brochure but it only explains at a high-level.
A normal standalone SA won't perform close to DC, so that functionality would likely be missing on a typical workbench if the 'scope didn't implement it.

I used to feel the same way, except that the standalone AWGs tend to have a lot more functions & power. I needed a counter, and my SDG2122X has that. Then I needed an AC voltage source, and it works great for that too. Even the DC offset can be used to some extent. There's a lot of bonus features I didn't think of before that really work great on standalone AWGs.
