Hi guys, I am currently generating LTE signal and receiving it through Agilent MXA signal analyzer. When MXA shows the transmitted signal, it shows the transmitted signal+noise.
Then, there is MXA's instrument noise. How can I measure the SNR practically? Because if I turn off the transmission and just measure the instrument noise, it will be all wrong because from transmission I will get noise as well.
Please advice or share you experience.
Thank you.

The nominal value for the accuracy of an LTE downlink EVM measurement can be found in the MXA datasheet. This will give you an idea of what the worst case expected EVM contribution from the MXA should be, and what portion of the EVM result is from the input signal.
