Hello marmad,

thank you.

Best Regards

marmad:
Having heard back from Rigol (via our good friend Drieg), it appears I was mistaken about the following bug:

When both channels are on, any memory read that requires more than one packet of data will ALWAYS fail. The maximum packet size is around 2MB - so any memory depth >2MB for byte mode or >~200kB for ASCII mode can not be read correctly.

In fact, it works fine. The thing that was confusing my software is that, with a single channel on, the two SCPI commands used to test and then read the buffer (:WAV:STATus? -> WAV:DATA?) both return the same number of bytes to be read from the DSO. But with two channels on, the commands return different numbers, with the WAV:DATA (not STATus) command containing the correct number (i.e. the DSO has filled it's buffer further after the STATus command).

So I've removed this bug from the bug list - which, BTW, is reportedly down to virtual NIL in the upcoming release.

So I just got my DS2072 and teneyes ask me to post up info on my firmware and fpga etc... well here's what it shows...

He also asked when the last cal time was from the self cal menu and that is showing as 2011-01-01 00:00:00...

so what's the consensus on the most stable version for a noob to upgrade from 00.00.01  :-DD

Hydrawerk:
Well, it might happen. I bought my DSOX2002A in April 2013 as a new unit from Farnell. I got a scope manufactured in July 2012.

To get your correct FW version, read the bottom portion of this post.

The self-calibration date is meaningless - it's just the earliest date/time stamp the DSO can show (i.e. no self-cal has been run); factory calibration data is not stored in the DSO - it's on a piece of paper that comes with the scope.
