New Keysight 4 Channel Scope (1200 X-Series)
<< < (7/17) > >>
Mr. Scram:
That's unfortunate. Fan noise is one of those things which make a huge practical difference, even though it's often completely invisible on the specifications sheet.
PixieDust:
Still no reviews of the thing? :scared:

I'm also reading that the base model Keysight scopes are made by Rigol. So why the price premium?
Keysight DanielBogdanoff:
@hugo, noted.

@Mr. Scram it sometimes gets put in the data sheet, but only when we're trying to make a point :). I have heard of some people putting quieter fans in other scopes.

@Bud, that is really odd! How often does it happen?

@PixieDust The old 1000s may or may not have been third party ;). The 1000X, however, is different! Our Keysight-only ASICs and everything.

Oh I see, yep, the comment I  saw was from a while ago. Now things make more sense.

The 1204 has a temperature-controlled fan - implemented as a linear regulator on the main PCB - this adds cost so clearly KS thought it important.
I've not run it long enough  to see what power it runs after fully warmed up, but at startup it is very quiet
