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.
