1. The DP932U is also Android?
2. Why are you assuming that the DP has the same licensing implementation error as the HD scope?
3. This is a pubkey. You'll never be able to license it with the specific stock key. Or did you replace it?
4. If you did replace it, did you change it in the FRAM or it doesn't get stored there also?
1) No it's openwrt (TinaLinux)
2) Not quite sure I've understand. I've seen in the Rigol website it's possible to buy these three licenses: HIRES, ARP, DIGITALIO.
3) No I haven't. I have not enough knowledge on this system and how these key works to generate a serial.
Please if you know something more I will be pleased to learn how it works. We can modify the go script to generate this serials as well.
