Hi,
I recently got a  MSO1074Z-S which is at version 00.04.01.SP2
I tried to add features but did not work either for me.

Any hope to get a rigol utility update soon ?

thanks

I've got a memory dump of my MSO1074Z-S if anyone wants to have a look into it.  PM me if you're interested.  Its about 8MB compressed.

There was a time when the DS2302 (300MHz) mode was buggy with the 00.02.01.00.03 firmware.  Did the 00.03.00.01.03 version correct the issues?  Is there a downside to running it as a ds2302 compared to a ds2202 any longer?

Your serial number starts with "DS1ZD" and my serial with "DS1ZC". The following six numbers are the same, except for the last three numbers.
I suppose the "D" is for the model with the signal generator (MSO1074Z-S) and the "C" is for the model without sig-gen (MSO1074Z).

I 'upgraded' my MSO2072A to a MSO2302A; so far I have had no issues.  The I2C decode seems slow, you can't look at the decode real time, you have to capture a single shot and then you can see it go past doing the decode.  In this respect, having such a large memory is clearly an advantage, I have a Tektronix MDO2024 at work and it's annoying that you can capture a section of I2C with decode but when you start scrolling through the message chain, it quickly craps out because it's run out of memory.  I'll check on the software versions on my MSO2302A and update this post.
