Reply To: SA124B vs BB60D

Right now the immediate need is to test an HPA. It has an SMA input port. I believe the system will have some version of QAM but I’m not entirely sure.

So if I read your response correctly the spectrum analyzer has an output that drives an input to a DUT (in our case an HPA) and take the DUT output and find EVM etc. So the spectrum has the ability to be an input device along with it’s normal function of being an output measuring device. Very interesting…I didn’t know that.

BTW, I assume the SP145 has a similar function…???

Thanks
