REVIEW - Rigol DS2072 - First Impressions of the DS2000 series from Rigol
Daruosha:
I couldn't find the maximum input voltage in 50ohm input impedance mode and the manual says CAT I 300 Vrms, CAT II 100 Vrms with Transient Overvoltage 1000 Vpk only in 1M ohm impedance mode.
Does anyone know the proper input protection figures?

Are you sure it's not listed on the front panel alongside the BNC inputs ?
Normally in 50 \$\Omega\$ input mode max voltage is only 5V, so take care or you'll damage the inputs.
Daruosha:
Ooops!! Yes, i looked everywhere but the writings next to the BNCs :palm:
Well, i was trying to find a proper attenuator for measurement and I knew the common 5V limitation, however I had doubts about it and well... Thanks :)
Still, it's not been mentioned in the manual :blah:

The manual supplied or their latest from their website ?
There might be a later revision online so it might be a good idea to check.
MrFox:
I finally bought a ds2072a after months of browsing among a bunch of imperfect choices. Siglent and instek were also very interesting for the price. I'm a bit worried the ds2000a series is getting old and they're probably coming out with a new model soon, but on the other hand I'm not buying a brand new chinese scope then wait years for bug fixes, and hope for a hack too. Life is full of compromises.
I guess it's basically my first real DSO, the first building block for my brand new home electronics lab. The last serious scope I used was over 20 years ago at school (we used mostly HP 54600A and a bunch of analog Tek), and the only scope I owned for myself was a BK 1471B, which I used for my first job, some dotcom startup, then moved on to programming jobs. Now I'm slowly coming back into the hobby with a bit more time on my hands, and a budget for useful equipment.
Big thanks to everyone making the hack possible! :-+ It worked fine with mine, the only issue was that I had to use rigup 0.4 (0.4.2 didn't work).
Firmware: 00.03.04.02.01
Hardware : 2.3
Edit: Updated to 03.05, worked fine. There's a small bug with X/Y, if you scale down to 500uV and back up, it misses one step until you refresh it (either with run/stop, or touching any of the channel options which makes it refresh it correctly).
Also, I haven't seen this mentioned anywhere: DS1000 and DS2000 started bundling the new PVP2350 probes, while the RP3300A is discontinued. The new specs are interesting, it's 35MHz at 1x which should makes it really useful for measuring power supply noise. Only 10pf at 10x so it doesn't look compromised there either. However the compensation pot is on the probe, I wonder if that will cause issues, or if there might be a compromise at 10x in the design to allow the surprisingly high BW at 1x. I thought the high frequency probes always had to put it on the BNC end???
