Which should I go for ? SDS1202X-E vs DHO812

(1/3) > >>

kenkit:
The  SDS1202X-E  has 2 channels and supports upto 200mhz with  100,000 wfm/s (normal mode), and 400,000 wfm/s (sequence mode)
vs the  DHO812 with 2 channels with 100MHz and 1000,000 wfms/s.
I intend to use it in electronic projects e.g find clock lines on phone repair emmcs and also debugging spi/i2c signals mostly in phone/laptops etc.

ebourg:
The Rigol has better specs than the Siglent, but don't buy the DHO812, for the same price you can get the DHO804 with 4 channels and then upgrade its bandwidth. An upgraded Siglent SDS802X-HD may also be a good choice in this price range.

You probably need 4 channels for SPI.

But either way: Don't buy the expensive model, buy the base model and change it to the expensive one. The hardware is the same, it's just a configuration file on the internal disk.

Not technically correct when a DSO provides a Clock Timeout setting for protocol decoding which SDS1202X-E does.

SPI is usually "more than two" wires.

(and even Siglent doesn't make a 3-channel model, so four channels it is)


PS: Rigol has triggers, too, believe it or not.
