content: Hi all,I think it's probably time I move on from my Tek 465M as my primary scope, as lovely as it is.I've been intrigued by the GWInstek MSO-2014EA for a while. 100MHz, 4 channels, 16 channel logic analyzer, dual channel 25MHz AFG, $1,350. GWInstek raves about the built in spectrum analyzer in their MDO line, and I believe the MSO line has the same spectrum analyzer specifications/features.Has anyone used any of these newer scopes? MSO or MDO? If so, any opinions on them?Thanks.https://www.tequipment.net/Instek/MSO-2104EA/Mixed-Signal-Oscilloscopes-(MSO)/

content: I've got the MDO-2204EX with the SA you mention, and it is really high resolution and high update rate. Even with 1Mpt FFT resolution you get two digit FPS update rates, so I'll have to agree with the advertizing material - It is really really fast and high resolution.Another cool feature is that you can adjust the display in the frequency domain exactly like I do on my SSA3021X. It's a big convenience factor that you don't have to switch to time domain and adjust the resolution indirectly by changing the timebase. You can set Centre, Span, Start and Stop frequencies so it's quick to zoom into areas of interest.The auto measurement function is also nice to work with. You can define the size of a peek table and it will automatically show the amplitude of the number of highest peaks you selected and mark them on the trace with real time updates.All in all I think these scopes are incredible value for money. I have replaced a $20K LabView NI rack with this $2K multiscope for desktop and fault insertion testing. The LabView driver is really simple to get running. It's also nice to use for manual measurements. I've even bought two for work because I prefer them over the Keysight 3000 scopes we normally use. It's been a really positive experience so far (for me at least ... YMMV!).

content: Hey. Thanks for the reply. I have another thread related to GWInstek scopes here:https://www.eevblog.com/forum/testgear/which-scope-manufacturer-provides-the-best-user-experience/50/I decided to go with the GDS-2074E. Decided against the MDO/MSO line, after decided I didn'tneedthe spectrum analysis capability. Though, I didwantit. We'll see if I regret buying the GDS instead of the MDO somewhere down the line.And note to anyone else reading this: MSO line doesnothave advanced SA features. MDO line only.

content: Well, I have an MSO2204EA running V1.34. It *does* have the SA function, but when I mentioned it to Instek, they removed it in 1.35. It was part of a demo for the MDO line, but I discovered I could break out of the demo and use it. But it will only work if the unit has the AWG.Now I have an HP 8560A w/ TG and an MSOX3104T. The fate of the Instek is at present unknown.

content: Quote from: rhb on June 10, 2018, 07:49:43 pmStrange that they would intentionally cripple the MSO line functionality when it most likely has the same hardware as the MDO line.That's not in line with their policy of enabling all SW options on the MSO/MDO line of scopes.We also use the MSOX3K line at work, but I like the MDO scope better (even though it's only 20% of the MSOX price here in Denmark).

content: Interesting - I don't see a version 1.35 for the MSO scope2 on the GW website, only ver 1.34.

content: I'm sorry, V1.32 is the one with the SA still functional on the MSO2204EA. V1.34 removed it. V1.35 fixes issues in the trace math but has not been released yet.
