And you are right - "doesn't work as expected" is not a bug, but if you do not have decode on recorded data the decoding option is not worth the money. And I was about to buy the decoding option before I try to hack it ... because well if they did a great job, they deserve the money. But I tried the trial option and I was not quite happy with it. Decoding seams to be there for the marketing - just an answer to Agilent's decoding option. |

Thank you very much, zombie28 and tirulerbach! It took some time for me to figure out the right sequence. So I've managed to write it down. --- Code: ---Device: DS2xxxA. No need to open it and buy any other stuff. 1) Flash DS2xxxA with patched FW (license key dumping, from zombie28: https://mega.co.nz/#!FFk10SCY!UuWPXyqZwmca00pa2clOth1ryh1Z-AAgJg2yibfoUw0). 2) Connect DS2xxxA to a PC. 3) In "Rigol Ultra Sigma" open "SCPI Control Panel" and "Send&Read" string "*IDN?" 4) Copy answer to text file. 5) Copy string from comma after serial # of your DS2xxxA to the end ("02008400..."). 6) Open HEX editor and paste string as HEX (not ASCII). 7) Copy serial # of your DS2xxxA. 8) Append serial # as ASCII to the data in HEX editor. 9) Append "00" as HEX. 10) Save file as "keyfile.bin" to folder with "rigup" (from tirulerbach: https://mega.co.nz/#!qAkUkTZB!XG12bUKhIz4CmQt6DbBnGRMvEe5AvUjEaBxi4R03tw8). 11) Open command line and navigate to folder with "rigup". 12) Execute "rigup scan keyfile.bin" and get some keys: RC5KEY1: 88359067012Exxxxxxxxxxxxxxxxxxx RC5KEY2: 3D44CD4EC48Fxxxxxxxxxxxxxxxxxxx XXTEAKEY: 95F6CC12864Axxxxxxxxxxxxxxxxxxx PUBKEY: 006CE7F7xxxxxxxx PRIVKEY: 008ABBC4xxxxxxxx SERIAL: DS2D154xxxxxx 13) Copy them to another text file "keyfile.txt" in "rigup" folder. 14) Execute "rigup license keyfile.txt NSxx", where: NSEH (0x1C087) - All options NSER (0x1C08F) - 100 MHz + all options NSEQ (0x1C097) - 200 MHz + all options NS8H (0x1C0C7) - 300 MHz + all options 15) Copy license key. 16) In "Rigol Ultra Sigma" "Send&Read" ":SYSTem:OPTion:INSTall YOUR-LICENSE-KEY-WITHOUT-DASHES". --- End code --- Everything worked fine and now my DS2072A became DS2302A with all options! After that I reflashed to last original FW (non-modified 00.02.01.00.03) and all options stayed in place. |

If you are using AUTO trigger change it to NORMAL and try again. --- Quote from: johna on February 04, 2014, 08:49:35 am ---My test was on unhacked unit.

--- Quote from: excapealex on February 03, 2014, 07:51:49 pm ---The new method can also work with the DS2072A-S (with 2 channel function generator)? Has anyone tested on it? --- End quote --- That you know.. updating a DS2000A-S with the patched FW there is a risk of losing access to the signal generator? Having not yet made the purchase.. Do you know how the function generator is managed? As example: When pressing the source button it switches to a separate management (as a second instrument) or is a more integrated management? |
