New toy(?) scope, DSO154pro, 1ch, claimed 40MS/s

<< < (4/19) > >>

Matamipru:
Strange 1mhz or 18mhz. Strange 40msa or 16kbps 50ns ... Sure the chipset accepts sensitivity of 10mv or lower

Fungus:
I got mine this morning.   :)

Much smaller than I expected - literally the size of a credit card! (but 2cm thick...)

Battery came charged so I just turned it on and it worked.

Menus are very easy to navigate, it all seems to work as expected. Didn't need to read the manual.

For 30-odd Euros I've got no complaints at all!   :-+

Hi, I tried the rise time bandwidth calculation method mentioned by Fungus in another thread.

On the attached picture, PSU output was 1.34V checked with DMM. I did try other values but the results were always about the same. So if I'm getting it right, bandwidth would be about 9MHz? Half the spec?

Well, it has been a happy hour anyway.

I would love to use my Rigol DG811, after the upgrade, it should be good until some 60 MHz. However I think I'm missing something. Using coax+50 ohm terminator, atenuation should be set to 1x, but then the bandwidth would be lesser?

Edit: typos

 

Fungus:
Here's a 5V, 16MHz square wave on mine:


I just connected it up and pressed "Auto". It locked onto the signal no problem.

As expected you can only see a sine wave, but it's there....  :popcorn:

tatel:
So you simply put atenuation at 10x with coax+terminator?

Edit: ni de coña... this has to be the probe. I see your screen shows Zeeweii, mine doesn't. Different software versions perhaps? My square wave becomes sinusoidal sooner
