It seems Dave92F1 has provided a superb method while we all stand on the shoulders of giants (Peter, rigup).
Dave's method:
YET ANOTHER HACK SUMMARY
I had all options + 300 MHz on my DS2072A, then I upgraded to the latest firmware, and lost all the hacks. It took me some time to figure out how to get them back.
This is my summary (should work for a new out-of-the-box DS2072A as well):
1 - Download & unzip the latest "Rigol Bildschirmkopie LAN/USB" from
http://peter.dreisiebner.at/rigol-bildschirmkopie-lan/2 - Connect scope to LAN.
3 - Run the RigolBildschirmkopie.exe, click Device>Select>Search>Select.
4 - Do Device>SCPI-Command, then Send & receive ":SYST:UTIL:READ? 1,33554432".
Wait a long time (~5 to 10 min) for it to complete.
Click Save, save it as "memoryDump.scpi" (save this file for future use!!)
5 - Download and unzip Rigup 0.4 (or later) from
http://gotroot.ca/rigol/.6 - Open a command window where you unzipped Rigup 0.4, copy memoryDump.scpi into the same folder.
7 - In the command window do: "rigup ds2072a memoryDump.scpi"
This will produce an output something like:
rigup ds2072a - Version 0.4
Serial number: DSxxxxx
NSEH: JPJQLFK-G3QNRLU-WFFFZMD-xxxxxxx All options, no bandwidth upgrade
NSER: 8NXBL2U-JE2LZL7-9NEN5XK-xxxxxxx All options, bandwidth 100 MHz
NSEQ: R939MMG-NR63H25-9H993PX-xxxxxxx All options, bandwidth 200 MHz
NS8H: G2YRFYX-D589HNR-4K8YW3H-xxxxxxx All options, bandwidth 300 MHz
8 - rigup scan MyKeys memoryDump.scpi
This will write your keys to the file "MyKeys".
9 - rigup license MyKeys NS8N
This produces an output something like:
5P89ZX7-LYMCTCS-P4PQ792-xxxxxxx (NS8N = 0x1C0C3)
10 - Run RigolBildschirmkopie.exe again, click Device>Select>Search>Select (again).
11 - Click Device>SCPI-Command, then send & receive:
:SYSTem:OPTion:INSTall <key to the right of NSEQ in step 7>
The key (from step 7) MUST have the dashes removed.
For example:
:SYSTem:OPTion:INSTall R939MMGNR63H259H993PXxxxxxxx
At this point you should have all options + 200 MHz.
12 - Click Device>SCPI-Command, then send & receive:
:SYSTem:OPTion:INSTall <key from step 9>
Again, the key must have all dashes removed.
For example:
:SYSTem:OPTion:INSTall 5P89ZX7LYMCTCSP4PQ792xxxxxxx
That's it; you should have 300 MHz + all options now.
Maybe you can skip step 11 - I haven't tried it that way.
If you mess up, no problem. Just send ":SYSTem:OPTion:UNINSTall" and start over.
Only minor tweaks I can add are :
Step 2 : Connect to lan so the scope can obtain an IP address and be recognized on your ethernet.
Step 4 : Do Device>SCPI-Command, then Send & receive
":SYST:UTIL:READ? 1,33554432". Remove the first colon so that it now reads
Do Device>SCPI-Command, then Send & receive
"SYST:UTIL:READ? 1,33554432". Make sure there is a space after the question
mark.
Step 6 : After the command window is open use DOS commands "CD" to change the directory until you are in the correct one.
Step 11 : Do this step just as he notes. He suggests an option to leave it out, but others did not get a complete install unless they did step 11 and then step 12.
Minor tweaks really from this newbie. Can't say enough about the knowledge brought together at the eevblog. As Dave Jones would say : AWESOME !!
