MSO5000 Bode Plot Capability: Is it Good Enough? [Many tips about a 1st scope]
<< < (17/55) > >>

Another option would be a modern Micsig oscilloscope combined with Analog Discovery for the bode plots.  :popcorn:

Micsigs are a joy to use. (it's what I own)

Analog Discoverys have a 14-bit ADC for the bode plots and can also do logic analysis for your Arduino.


Edit: You can download the Analog Discovery software and use the "analog" part for free with your PC sound card. It does oscilloscope, spectrum analysis, bode plots...

Both can be answered by someone who works with all of the mentioned scopes - And then it´s his own impression.
In my case, I got following "scope owning history":

- Rigol DS1000Z
- Rigol DS2000
- Siglent SDS1104X-E
- Rigol MSO5000
- Siglent SDS2000Xplus
- Siglent SDS2000X HD (actual scope)

GW Instek never came into my mind, maybe they making good scopes and nearly nobody knows about, or they knowing about it and this may explain their place by the hobbyists.  ;)

Interesting. Two questions:

1. Why did you switch from the 2K plus to the 2K HD?
2. How did the MSO5K compare with the SDS1104X-E *purely in terms of noise and OS/UI quickness*?

Thanks.

Sorry, overlooked this...

1. Because of the 12bit - To be honest, it´s a buy for the "future" when I´ll need to have 12 bit resolution, actually I didn´t need it urgently.
Most of the hobbyists won´t need this... ;)
In general you(and others) would be surprised how "less" you really need...
I had the 2000X+ over 2 yrs, ordered three for our testfield at work where they´re used everyday without any issues.
The 2000X+ is (in my opnion) the benchmark what "lower midrange" scopes concerns.
Yes low, the 1400€ is "nothing" in the scope world...
I´ve also ordered a current probe from siglent - It costs over 1000€ more than the three SDS2104X+ together...

2. This is a little bit "unfair", as the MSO5000 got a more complex UI in compare with the 1104X-E.
The touch response is indeed a little bit "laggy", but you can avoid it by using a mouse.
Fan noise was annoying, after the upgrade it was less but still hearable.
Noise on the 1104X-E was similar to the MSO5000 after it´s upgrade.
In both cases not really silent but this is only disturbing when it´s totally calm in your room.

That is a good option as well but would exceed the total budget.

It's in the ballpark of an MSO5000.

I'll echo 2N3055's opinion here. Sounds like someone who doesn't understand what they need or why.
If this is for beginner hobby use, then any instrument that supports bode plots will likely be fine.

If this is for actual design use where parameters are critical, then you'd either be:
- Using a dedicated device (as mentioned above, eg audio specific)
- Using various equipment with USB/LAN capability and pulling the data into your own plotting setup on a PC
