+## Hardware Setup
+
+You need a few things:
+- [Analog Devices Pluto SDR](https://www.analog.com/en/resources/evaluation-hardware-and-software/evaluation-boards-kits/adalm-pluto.html).
+Any variant of the Pluto *should* work too such as the [Pluto+](https://github.com/plutoplus/plutoplus?tab=readme-ov-file) however I have only tested with the basic flavor.
+- Directional couplers (1 per port up to 4 ports).
+I have been using [AAMCS-UDC-0.5G-18G-10dB-Sf](http://www.aa-mcs.com/wp-content/uploads/documents/AAMCS-UDC-0.5G-18G-10dB-Sf.pdf)
+- Charon switch board - coming soon.
+Without this, you'll be limited to S11 and uncalibrated S21 measurements (with required re-cabling).
+There's nothing special about this particular board, if you want more than 4 ports you can make your own pretty easily. You just need 3 SPxT switches. Note that these switches will see tons of cycles so avoid mechanical switches.
+- SMA cables
+
+### Pluto Configuration
+
+Most of my testing is with Pluto firmware [v0.39](https://github.com/analogdevicesinc/plutosdr-fw/releases/tag/v0.39) though this may work with other firmware versions. Instructions for upgrading firmware are on the [Analog Devices wiki](https://wiki.analog.com/university/tools/pluto/users/firmware).
+
+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.

 ## Usage
 
 There will be some sort of GUI because that sounds useful.

 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.
