Rigol HDO-series license generator

• Obtain the IP address of the scope
• Connect to the scope using the Android Debug Bridge adb connect <IP of scope>:55555
• Download the unique key from the scope adb pull /rigol/data/Key.data
• Generate the license key using the rgtool program on the Key file go run ./rgtool.go
• Insert generated codes via SCPI interface on the website on the scope (http://<IP of scope>)

When not wanting to install adb or go, docker could also be used instead.

docker run --rm -it -v $(pwd):/workdir -w /workdir alpine \
  /bin/sh -c 'apk add android-tools && adb connect <IP of scope>:55555 && adb pull /rigol/data/Key.data'

docker run --rm -it -v $(pwd):/workdir -w /workdir golang go run ./rgtool.go
