Rigol DS1102Z-E vs DS1202Z-E
(1/2) > >>
Summerford:
Hi everyone,

(my first post here)

I am shopping for an entry level scope and I narrowed it down to the Rigol DS1102Z-E.

This model will surely do for my current interests (vintage radio restoration and occasional electronics repair) but I am tempted to go for the 200Mhz version, the DS1202Z-E, in case I need the extra bandwidth on future projects. The difference is just 60 EUR on Amazon. Any advice on this?

I have a second question. Looking at the specs of the two scopes (here https://www.rigol.eu/Public/Uploads/uploadfile/files/20221124/20221124215236_637f77244604d.pdf) the two models only differ in the "Bandwidth (-3 dB)" and  "Calculated Rise Time", as one may expect. But both models have 1 GSa/s sampling rate.  This suggests that also the lower model should be capable of handling 200Mhz bandwidth and maybe the functionality is downgraded by software.

Has anyone compared the hardware of the two scopes and found visible differences? If not - is there an available hack that can unlock the 200Mhz bandwidth on the DS1102Z-E?

Thx in advance

Hello,
I bought the DS1102Z-E in September 2021.
2 weeks after receiving it, I noticed trace brightness problems with the timebase at 5ns.
Other users found operating bugs. Rigol Germany and Rigol in China have NEVER responded to my emails complaining about the defaults of my scope.
In December 2022, the 2 traces flashed unexpectedly. So I sent this scope back to Rigol in Germany asking for a refund and I bought a Siglent scope.
You can see posts mentioning these defaults in this forum.
Apart from these problems encountered with the DS1102Z-E, if we close your eyes to these defects and bugs (that will never be resolved), it is a cheap scope that does part of the job.
Good luck.

Thank you so much for your reply!
I re-analyzed yesterday my needs and finally go for 4ch scope. Actually between siglent & rigol models and your review is very helpful as an experience w/ new rigols. I will check for messages also.
Thank you a lot!

I would try the Siglent route, Check the Buy/Sell for the recent amazon deals.
