I 've been experimenting with the option codes on my DS4024 and have worked out the various options. However, I was unable to change the model number/bandwidth.
It appears as though it may be done via a different means, such as hardware jumpers or other hardware configuration bits. Not really sure at this point.
Attached, and below, is what I have worked out. I suspect that the only people who will really gain from this information are the dealers who will be able to work out their own option licence keys to sell to customers, instead of getting them from Rigol.
Anyhow...
DS4000 Series DSO Option Codes:
Licence code string is in the following format:
LLLLLLL-RLGLLDS-****LLL-LLLLLLL

More Detailed description of Bits:
A - Control Bits
1. Option bank selection: Available options =1 (if = 1 then A.2 should = 0)
2. Option bank selection: Alternate options =1 (if = 1 then A.1 should = 0)
3. See Note(2)
4. Must = 0
5. Trial = 1, See note(1) : Official = 0
B - Control Bits
1. Must = 0
2. Must = 0
3. Must = 0
4. Must = 0
5. Alternating bit allows re-installation of the same licence, without uninstalling it (indicates "Option Installed!")
C - Control Bits
1. See Note(2)
2. See Note(2)
3. See Note(2)
4. Must = 0
5. Must = 0
D - Options (0 = OFF, 1 = ON)
1. RS232 Decode
2. SPI Decode
3. I2C Decode
4. CAN Decode
5. FlexRay Decode
Alternate Options (when A.1 =0 && A.2 =1)
1. Reserved (Empty Option)
2. Reserved (Empty Option)
3. Reserved (Empty Option)
4. Reserved (Empty Option)
5. Reserved (Empty Option)
Notes:
(1) Re-applying the same trial licence will extend the trial time by an additional 1932 minutes to a maximum time of 5796 minutes.
(2) If any one of these bits are = 1, then re-applying the same licence will result in the error "Licence Unavailable!"
If all of these bits are = 0, then re-applying the same licence will result in the message "The Option Has Been Installed!" or, in the case of a trial licence with maximum time reached, the message "Time Trial is Arrived!"
To work out the option code, use the following bit-to-code conversion table:
A = 00000
B = 00001
C = 00010
D = 00011
E = 00100
F = 00101
G = 00110
H = 00111
J = 01000
K = 01001
L = 01010
M = 01011
N = 01100
P = 01101
Q = 01110
R = 01111
S = 10000
T = 10001
U = 10010
V = 10011
W = 10100
X = 10101
Y = 10110
Z = 10111
2 = 11000
3 = 11001
4 = 11010
5 = 11011
6 = 11100
7 = 11101
8 = 11110
9 = 11111
Eg.
A) Option code to install SPI and FlexRay Decode Trial Options: 10001 00000 00000 10010 = T A A U
LLLLLLL-RLGLLDS-TAAULLL-LLLLLLL
B) Option code to install all 5 official options: 00001 00000 00000 11111 = B A A 9
LLLLLLL-RLGLLDS-BAA9LLL-LLLLLLL
Edit: use the above code you work out (eg. BAA9) along with your serial number and the private key to generate (eg. with RiKey) a license key. I only used the test key format above to indicate the placement of the code.
