new killer scope in town - a true game changer from R&S - RTB2002 & RTB2004
alonsojar:
Hi skander36
Thank you for your feedback. I'm not particularly complaining about the scope noise, in general my laptop (in fact an intel Nuc 11) is more silent than the scope unless I hit the cpu, but it's never close to be really disturbing.
I was doing some test because it's really easy to replace the fan and I was thinking that a Noctua will perform better regarding noise that the Sunon that was unknown brand for me. Since it was not the case, I forgot the idea and kept on the safe way.
Cheers

I'm a stickler for noise, I sold an Agilent meter because of noise.
I heard people complain about this but it doesn't bother me at all even after being on all day.
Martin72:
My (former) SDS2504X HD was "dead" in terms of noise, even with the original fan.
There is simply nothing like an active fan controller, but apparently this is only possible above a certain price range.

I dont think that the reason for an active fan controler is the price. Even in the cheapest oscilloscop there are more complicated circuts than an temp controler, which is so simple that simply its cost doesn't matter. I think that the reason for most fans are running at that speed is that the device has need of that airflow which the fan is assuring at that speed.
Martin72:
Then you could install the actually not expensive control system everywhere and, depending on the infrastructure, the fans would turn up to full speed faster than elsewhere.
Or otherwise, to follow the logic, you could have installed a weaker fan instead of a controller if the components don't get as warm.
In mass production, I look at every cent of material, especially if I have to offer the product at a low price due to market conditions.
In the price range where the RTB series is at home, there is a little more to it, so you can be "generous" and offer customers something for their ears.
