I want to buy my first oscilloscope, help! SDS1102CML+ vs Rigol DS1102Z-E

(1/1)

Hello everyone!, I am an electronic engineering student from Colombia :D and I want to buy a basic but complete oscilloscope. I'm between 2 options]:
1. SDS1102CML+ ($319)
2. Rigol DS1102Z-E ($279)
Del rigo strikes me that it can decode some signals such as UART and its memory depth of 24 Mpts
Which one do you recommend and why?

thanks!

BillyO:
Have you considered saving a bit more money and getting something like the SDS1104X-U?  It's only about 25% more money for a hugely better scope.

If the choice is between the Siglent 1102CML+ and the Rigol 1102Z-E, it's no contest.  The Rigol is far and away more capable than the Siglent.  They're essentially a generation apart.

You should read the spec sheets for both.  The measurement capabilities alone on the Rigol far outweigh the Siglent, as does the display (intensity-graded), the triggering functions (far more), the math functions (quite a few more), the sample memory (an order of magnitude more), the waveform update rate, etc.

I've had the 1102CML and the Rigol 1054Z (the 4 channel version of the scope you're looking at).  It's no contest between the two.
