Great comparative review!! Bought the Siglent 1202A and am quite happy with it so far. I need to calculate the energy in a pulse delivered into a fixed resistive load. Obvi, I just need to integrate the voltage squared. Can that be done?

Frank,

Thank you for undertaking this very time-consuming task and for doing it so well and in such detail. I saw at least one other observation regarding date of release of these models. I think the Siglent is the oldest of the three, having been released early in 2012. The Rigol and Siglent lines both continue to improve in quality and features. If you were ever to update this comparison, it would be interesting to see how the newer Rigol and Siglent scopes would fare, starting with Siglent's SDS1202X-E. While the 200 MHz bandwidth makes it an atypical entry level scope, it is one of the newest and it is the lowest cost of the Siglent SDS1000X-E series scopes. It offers 1 GS/s sampling speed, 14 Mpts memory length, and comes with serial decoding standard.

Just this week Rigol announced its answer to Siglent's entry level 200 MHz scope. DS1202Z-E is also 200 MHz, 1 GS/s sampling speed and it comes with 24 Mpts record length. It's MSRP is only $20 above that of the DS1054Z. Here's a look at costs of these units.

Keysight DSOX1102G $876 "typical price" according to Google

Rigol DS1054Z $349 MSRP

Siglent SDS1102CML $299 MSRP

Siglent SDS1202X-E $379 MSRP

Rigol DS1202Z-E $369 MSRP

Thanks to all those who have commented. It did take quite a bit of time but I learned things not only about the Keysight but also the two scopes I had already been using. The Keysight training material deserves a lot of credit as it is excellent.

This is a great detailed blog on oscilloscopes and test tutorials, that will be useful to a lot of us. Thanks for posting this, I appreciate the time it must have taken you.

Kind regards.

Hi Frank,

Awesome presentation and certain to be a big help for those looking for information on entry level scopes.

Really good Frank. I was reading this trying to compare it to the newer Siglent SDS1104X-E: I’ll have to do it when I’m next at the desk, although it’s a shame I don’t have access to the training signals.

Very good comparison of the three scopes.

Well done.

Frank,

Great comparison/write-up! There are a lot of differences between 'entry-level' instruments, but I wonder if the date of original release has much to do with the differences. Technology continues to move forward, and newer products generally have more features/performance than prior generation instruments.

Either way, that is a nice looking instrument.

Frank, thank you for sharing. It is a very instructive process for testing I will use too.

Hi Frank,

Nice 'scopes comparison! It's great that you managed to get traces across all the different machines where needed, it's a lot of work.

I believe the Rigol supports pass / fail masks and HW frequency counter too.
