 First bring-up of the prototype has been done with partial component assembly (missing few parts for one of the RF path). First bring-up of the prototype has been done with partial component assembly (missing few parts for one of the RF path).
 A [[http://www.leobodnar.com/shop/index.php?main_page=product_info&products_id=234|LeoBodnar GPSDO]] was used as a clock source for the PLL (in the final setup it'll also clock the Pluto). A basic ATMEGA328PB code was written in order to program the PLL at startup and enable the first lane mixer. A [[http://www.leobodnar.com/shop/index.php?main_page=product_info&products_id=234|LeoBodnar GPSDO]] was used as a clock source for the PLL (in the final setup it'll also clock the Pluto).

 +Not having access to te 26GHz SA for this test the PLL output was set to 3GHz and a tracking generator output around 2.001GHz, a Pluto RX set at 5GHz.
