Rigol DHO804 Test and Compare Thread

<< < (179/229) > >>

Fungus:
Who's going to be brave enough to buy one and find out if it has 50 Ohm when you change it to a DHO4000?

Martin72:
We already have a DHO1000/4000 Thread... ;)

bobxyz:
Can anyone comment on the web browser interface of the DHO814 versus the Siglent SDS1104X-E?
- Does it behave exactly the same as using the scope's touchscreen (or mouse) directly?
- What resolution does it support - just 1024x600 (or 800x480 for the Siglent) or is higher resolution available?
- Does it run at full speed, or is the update rate noticeably slower?

[background: I'm looking for a small quiet desktop scope for hobbyist use - generally 2-layer PCB debug, mostly digital with small amounts of analog conditioning circuits.  I have a couple old LeCroy scopes in the closet if I need high bandwidth, but the LeCroys are big and noisy.  Most of my debug time is spent in front of the PC on my bench - updating code, taking notes, viewing documentation, etc.  Having good web based control of the scope makes the debug and documentation (screenshots) faster and easier.]

The same as the 'scope.

Pretty much full speed.

It's also very easy to take screenshots and record videos via the web interface.

Indeed, and there has been said that the 50 ohm cand be activated with vendor.bin method as so the 800 MHz BW. But no real use without 2 ADC as the signal is halved and processed weird.
