The AD9363 receive chain is based on Direct Conversion technique.
Some things to think about:
Details on the performance can be found in the performance section.
While there are many aspects of receive performance, the two most common are:
For the ADALM-PLUTO, the both the receiver sensitivity and input accuracy are both frequency dependent. For plots vs frequency, check out the detailed performance section.
This is a the output of the Keysight 89600 VSA software, which is used to measure signal demodulation and complete vector signal analysis. In this case, we generate an LTE 10 (10MHz wide channel), and transmit it out the Tx port of the E4438C ESG Vector Signal Generator and capture it on the ADALM-PLUTO's Rx port, and the save the data, and load it into the VSA software for analysis. We can measure the RF offset (frequency error = 67Hz), and how accurate the 64-QAM constellation is created (an EVM of -43 dB, or less than 0.6% RMS error) - which is pretty good (better than the AD9363 datasheet).
By changing the LO frequency, output power, output attenuation, these results will change.
