This and the subsequent post mention an offset that self-cal doesn't fix: https://www.eevblog.com/forum/testgear/sniffing-the-rigol's-internal-i2c-bus/msg346806/#msg346806 I plugged the signal generator into the input, and indeed with 0mV offset on generator and 20mV PP, you can easily see the signal isn't centered on 0 (not just in 500uV mode either). Edit: I've got a DS1104Z |

nmz787 - use the scpi uninstall command (somebody posted a tool to do this not long ago) and then reboot your scope. Then reinstall a new key without the 500uv option. |

Hi All, (noob) I have been watching the DS2xxxn topic for a few weeks , I have Z's Patched F/W on a what was a 2072A. "Nice Job Z" However not wanting to turn up to the party empty handed (linux, Jtag & sharing Dumps are not my redeeming features) So I have been investigating other routes. I have found a DS2xxx SCPI command that appears un-documented and may be of interest if still supported in f/w. Having tried on my own unit I get a buss time out error, maybe patched F/W or maybe that all options are already installed, unsure?? It would be interesting to know what reply you get from a standard unit? or if anyone already knows about this CMD already ? SYSTem:OPTion:VALid? |

Hi! Guys, I am having problems with my RIGOL 2072 DSO modified to 300MHz. Is there a way to turn it back into a 70 or even a 200MHz model. I used the 3owl site. The fault is that I get screen messages "Parameter out of Range" when I know it isn't. I did the same tests with works AGILENT scope no problems. Also I can't put it into Peak Detect well I can but on using, it jumps to Normal. Thanks Guys Rachael :-+ |
