Sniffing the Rigol's internal I2C bus
Teneyes:
I just install new FW 00.03.00.01.03 for DS2000

As much as I can check the configuration was Not Changed . all Offcial
To me it looks like a Self-Cal will be required. ( different Cali. from FW00.02......
Easy to go back older FW

Use one of the On-Line Keygenerator (you want to use it for DS1000z) at* >
RigLol keygen: http://riglol.3owl.com
Canadian mirror: http://gotroot.ca/rigol/riglol/
UK mirror: http://rigol.avotronics.co.uk/mirrors/riglol/
Do NOT install 500uV Vertical Sensitivity, as it doesn't work properly (buggy*). Therefore do NOT use 'DSBA' - 500uV Vertical, or 'DSFR' - all options.
1. Type in your unit's Serial Number.
2. Type in DSER* for all options without the 500µV. This Option may not be in the Keygen's list, but it will work!
3. Do NOT enter anything for 'Privatekey', it will be inserted automatically for you (based on the DS1000z).
4. Press [GENERATE], and record the resulting Option Code.
5. When you are done enter the Option Code manually in the DS1000z using a single string without using any 'dash' (-) using Rigol's Procedure for activating the Trial Options in the D1000z. As I recall the procedure is available on Rigol's Web Site under DS1000z.
Hi all, my new DS1074Z has arrived. Applying the procedure of Ted572 using the code DSER all options ok. But the 100MHz increase has no effect, the minimum setting of the time base still in 5us. After unblock all the features I have typed in the key generated with the code DSEA, reset the Rigol but still in 5us.
Any suggestion? Maybe I,m forgot something?
Thanks

Did you check the model number in the settings on the scope? If it worked it will say DS1104z instead of DS1074z
icaro600:
Sorry guys, I have noted the model has changed to DS1104Z in the System Information window, so this is ok
By the way my firmware version is 00.02.03.SP5

I assume you mean 5ns, not 5µs. That's normal, the lowest timebase even on the 1104z is 5ns. With 100MHz of bandwidth, that's one period of a pure 100MHz signal per two divisions. It'd be nice to get a little more zoom, but eh.
Anyway the proper way to verify that the option is enabled is to put in a 100MHz sine wave and verify that it's no more than 3dB lower in amplitude than the same source generating a much lower frequency at the same amplitude setting. But then, finding a 1GHz bandwidth function generator is a tall order, so the REAL way to do it is to measure the rise time on a sharp-edged signal - a positive going digital edge from an Arduino is probably sufficient, but your function generator isn't: I know my Tek FG503 puts out up to 3MHz signals, but it has an output bandwidth of only around 7MHz so 3MHz square waves are QUITE rounded.
Anyway, once you know the rise time of an edge with assumed infinite bandwidth, rule of thumb is scope bandwidth = .35/(rise time). So if the rise time off my function generator square wave, is, for example, 56ns, .35/(56ns) = 6.25MHz.
