I am a beginner in this field and I am trying to understand how cubesats are tested.
Especially, I am trying to figure out how a transceiver is tested after it is assembled into a cubesat. For example, if the transceiver has RF input and output ports, and is not integrated, power stability, noise figure, ACLR, EVM etc can be measured by injecting the output signal to a spectrum analyzer. But how is it done when a conducted test cannot be performed, as they would not have a dedicated connector to plug the output signal into after it goes into a system? How can one perform a blocker test too? Are there on board softwares that would send these data to a groundstation software that performs these plotting?
Thank you so much in advance, and sorry in advance if I have not used the right technical term.
