BUYING ANOTHER DSO.

(1/3) > >>

MrsR:
Hi! Guys,
I am looking at buying a RIGOL 100mHz DSO and I was wondering how I buy it in Australia so
DAVE gets his 6% cut.
Can't afford the the 2000 model so it will have to be the 1000 E model.
Have a question though " HOW MUCH VERTICLE NOISE BASE HAS IT "???????
I looked at the latest SIGLENT and it has 120Mv.
The ATTEN has 40Mv
RIGOL I don't know!! I understand the 2000 model has a very low noise floor at least RIGOL is advertising that it does.
I ask this as I do a lot of work with square wave and digital pulse and the more internal noise the wider the display line is and this can hide circuit noise. OK I am a bit picky but the Scope I have now the line is 3.5mm wide and this is the sixth one they have sent me under warranty :-DD that's Hysteria not laughter. I would still like Dave to get his bit. Bribery Dave I need some help with some Mosfet drivers in the near future.

Buy from Trio Smartcal and say on order it was recommended by Dave of EEVblog. Then pay the 6% as a donation to Dave on the Feed Sagan link on the EEVBlog main page.

saturation:
I measured mine empirically, and noise floor of the 1052e is ~ < 500uV with the input amp at max gain.  Note, noise rises with scope bandwidth.  There are charts and a discussion in the archives about sample noises from different brands and bandwidth scopes.

120 mega volts? Anyway, you might want to specify about which atten / siglent scope you are talking.

aghp:
And also important question, how it is measured. Very easy there go to comparing apples and plumbs.

I have looked  Siglent SDS1072CNL and it looks like 5mV/div settings it have around < 1mV (measurement show 0.80 - 1.0mV p-p noise without DSP filtering.  Now it is also good to know that it looks like Siglent do not use cosmetic cleaning filters for "nice trace". (yes it may make it more fast wfms/s)  and user can set adjustable digital filter separately to both channels and then you still may have full BW but reduced noise!)


Then old: (today there is Owon 2.8.2 and even (marginally) less noise)


Here some test with old workhorse Tek TDS520A and Owon SDS7102 (not V2.8.2)  face to face..

This is good to read also:
