-### Power Calibration
-I include a default output power lookup table. This is derived from two TX channels of two Pluto SDRs and does not include any of the loss of a coupler or Charon switch board.

-Absolute output power is generally not well calibrated for VNAs anyway and has negligible impact on most measurements so this is probably sufficient for most users. If you're trying to run a power sweep this may be insufficient.

-If you have an RF power meter you can generate your own power calibration.

-Note that unlike the main calibration, power calibration frequencies do not need to match the measurement frequencies. Values are interpolated.

 We need two receive channels on the SDR. If you have a Pluto+ that should already be configured and you can skip this step.
 
 Analog devices has a [guide](https://wiki.analog.com/university/tools/pluto/users/customizing#updating_to_the_ad9364) for enabling the second channel. Ideally this should be set as `ad9361` to enable a wider band of operation in addition to the second channel, however the critical setting is enabling 2r2t.
