1. Connect Urukul's output (see booster template for exact ports) to the Booster's input
2. Connect Booster's output to the oscilloscope with load
3. Measure it's RMS, convert to dBm, put it to the measured cell
4. Get the output value from telemetry (see booster template for exact path)
5. Disconnect the Booster's output
6. Get the reflected value from telemetry
7. Do steps 1-6 for second Urukul's output
8. Fill in `slope` and `offset` from settings for output and reflected curves
9. Do steps 1-8 for every channel
3. Raise channel's `output_interlock_threshold` to 40

13. Do steps 1-10 for every channel
_Note: default setting values are usually the same across channels, so you can extrapolate them for all channels._
