New toy(?) scope Fnirsi DPOX180H, claimed 180MHz/500MSps (May 2023)

<< < (99/113) > >>

Serhii74:
I don't have this problem until 20 MHz. And at a higher frequency the generator does not allow me.
Maybe you didn't switch to 10x mode on the probe? As the manual for the oscilloscope and probes advises, at frequencies above 5 MHz, switch to 10x.
On the attached screenshots, on the first channel there is a probe from the scope of delivery of the oscilloscope, on the second channel there is a direct probe without a BNC-BNC attenuator.

Rooster Cogburn:
Apparently the new housing is sold separately:

Instead of cases they should solve serious problems this scope has. In the meantime it's the same "marvellous" piece of unfinished technology. save your money.

RAPo:
I've got a chance to test the new case.
I must say this is an improvement.

The buttons are not as stiff as the original version.

The probes are more accessible to insert if you have fat fingers (like I have).

Of course, the inner workings have not changed.

 set FG to 1KHz Square Wave, 2 Vpp, 50% duty

press Auto

Press H+ until H=1us (top indicator) watch the glitch

Keep pressing H+ until H=5ns watch the glitches on the waveform 

Bellow 32KHz is useless, we can't trust anymore on the displayed image if we zoom in (not zoom button)

It's also seen at 0.4, 1.8, 3.6, 5.4, 7.2, 9kHz and many more flavours

New dress, same old ....  :palm:

Fnirsi simply don't care about solving important bugs, instead they launch a new collection of dresses for the same doll  :-DD
