Hi everybody, I have a DS2072 (without A), hardware version 2, so 50 Ohm input resistors plus relais are build in. I have pimped this scope (thanks, thanks, thanks and much more thanks to cybernet and all other developers !!!) to DS2302 with all available options. Now my question: Does everyone knows, is it possible to change the inptut impedance like the "A"-Version between 1 Mohm and 50 Ohm directly at the scope?? Thanks a lot for your help....

I'm pulling my hair to get the 1ns timebase (DS2072, HW 2.0). If I do option uninstall (and re-install with DSHH, but not mandatory) the scope stays in 500ps timebase until the next reboot. If I leave it at 500ps and reboot, it stays there until I touch the knob. Then it is stuck at 2ns and that's it (nothing below 2ns). Thanks. LE: It seems that I didn't do my homework well. So the patched firmware is not required and the 1ns timebase should be enabled by 300M option (included in DSHH). Unfortunately, the model stays at DS2202 (I was expecting DS2302, right?) and the timebase doesn't go below 2ns. Is there something that I do wrong in the following steps? - uninstall all options (confirmed on-screen) - power-off - power-on (tried with F6 and without it, doesn't matter) - apply license code generated by using DSHH. Confirmed by the scope and checked in options menu (300M is the only bandwidth option there) - model is DS2202, minimum timebase is 2ns I'm using a python script for writing the commands through SCPI. If the scopes confirms commands and applies the license, I assume it doesn't matter that I don't use the scope GUI for that. |

Did you re-post it? Yesterday it wasn't available. Thank you. LE: It seems that this fixed it. Steps: * un-apply key * downgrade to riglol 2302 version * reboot once more. Model changed to DS2302 * apply DSAZ key * re-boot * upgrade to latest firmware. lost all options(?) * apply DSHH key Outcome: * mode stuck to DS2302 * timebase goes to 1ns Thank you again. |

Hi, --- Quote from: Dave92F1 on February 23, 2014, 06:16:16 pm ---I got 300 MHz working on my DS2072A (I was only able to get to 200 MHz before; "NS8H" didn't work). I did it by installing Zombie28's patched firmware (this allows the DS2xxxxA to use the old DS2xxxx option keys): https://mega.co.nz/#!FFk10SCY!UuWPXyqZwmca00pa2clOth1ryh1Z-AAgJg2yibfoUw0 Then, instead of rigup, I used the install key generated by http://riglol.3owl.com/ (mirrored, I think, at http://www.gotroot.ca/rigol/riglol/ - note that you can download those web pages and run them locally if you want), using "DSHH" to install "all options". That worked! BTW, that patched firmware doesn't recognize any options that were installed with the standard firmware (the options disappear). Not to worry - you'll get them back when you install the key generated as above. --- End quote --- I just wanted to give a shout out to Dave92F1. Just got a Rigol 2072A. Followed the guide posted here by Giggy as to how install the firmware from Dave92F1's post, generated the key code. Entered it in the 'scope, rebooted, voila, I have 2302 now. It is great 'scope for the money, no beef. starting to wonder if it would be worth buying an entry level 6K... For now this one will help a lot though. FWIW, my 2072A was shipped from the factory in late Dec 2013. Great stuff, ThanX to Giggy and Dave92F1! Greez SSAL |
