MSO5000 Bode Plot Capability: Is it Good Enough? [Many tips about a 1st scope]

Only affect some models, certainly not all and is a mimic of the LeCroy way of managing captures.

It IS tricky when you know what´s behind the fan thing - Most didn´t and simply exchange the fan.

Yepp, thermal design is the keyword although I have doubts in some cases, manufacturers are taking care of this.
For example the MSO5000... ;)
As known I´d give mine away for modifying it by rigol itself(Display, Fan).
It came back and was hearable more silent - They simply took a resistor in series to the fan, no fan exchange, no regulation implemented.
But the scope was getting significant warmer so I´ve asked them, if this was proofed before and they answered yes.....yes it´s no problem.
Aha... ???

Signing this.

Yepp, most manufacturers don´t follow this and letting the flow going anywhere.

But in the end low noise starts with a well thought out thermal design that includes things like directing the airflow. I have a Dell workstation which is whisper quiet due to the airducts that direct the airflow to the places where it is actually needed. The Lecroy Wavepro 7k OTOH has no airflow design at all so it needs a crapload of air and a lot of it goes nowhere.

As you may imagine, I agree about the overload on the brain.
And I learned how important the airflow is by months of trial and error in my journey into building a silent computer. Also, fan grills and filters do impact upon noise and air pressure and airflow up to some extent.

If that's it, then the AD2 doesn't do it. It lets you zoom out, but what limits it is the sample memory. As long as you're sampling at 100MSPS and have configured it for 16384 points for the scope, you'll be able to get 163microseconds of record, even if you stopped the acquisition at the fastest timebase. When you are sampling at a slower rate, it's because now it needs to reduce the sample rate to fill the sample memory, and at some point, it will be just enough to fill the screen.

Thanks man, I didn't know that. I'm still delving into the manual, there are a lot of things to learn for such a small and apparently simple device.
Let me ask you: is there any way to get a log sweep out of the AWG? Thanks!

And if you look into source, signal generating part is separated in module and can be replaced with code that drives some other generator... In fact there are preparations in code for it..

That's very good news. If it's witten in Python, I have some programming experience with it.
Thanks!

It is not written in Python. Sorry!
