We are using the AD9373 at 153.6MSPS RX sampling. what is the SNR we will get at ADC Full scale.
Evm vs input power graph is given in datasheet. At low levels of power,EVM=SNR.
The ADC SNR will not be valid when tested as a full signal chain. Hence the best data available is the value of the snr provided in datasheet.
It dint seems correct!!
the RX EVM for the AD9371 shows 1% from -40dBm input power. and it degrades at -60dBm input power, ADI app not suggest to have 20dB gain to get -101.5dB Sensitivity.
What is the wave form they used for EVM Vs Input power plot in Datasheet??
What is the EVM spec at Reference sensitivity that ADI Suggests??
Even with 20dB gain we will get -25dB EVM @ -80dBm is it correct??
What will be the RX EVM at -101.5dB Uplink Waveform??
Waveform used is ETM3.1 , 64 QAM modulation.
Above graph is with signal at Rx input and AGC enabled.
I guess since LNA is not included , Noise Figure of chip also needs to be considered in calculation.
