Hi,
I've received AFE7950EVM and I'm trying to begin with the simple loopback test (JESD loopback from ADC to DAC).
Latte gives example desing for this, called AFE79xx_EVM_Mode5.
In that mode NCO frequencies of ADC and DAC are set to 3500 MHz.
For now I have the signal generator and spectrum analyzer up to 3 GHz.
Would this params work, if I change the NCO frequency to 800 MHz, for example?
Like this:
sysParams.txNco0 = [[800,800], #Band0, Band1 for TxA for NCO0
[800,800], #Band0, Band1 for TxB for NCO0
[800,800], #Band0, Band1 for TxC for NCO0
[800,800]] #Band0, Band1 for TxD for NCO0
sysParams.rxNco0 = [[800,800], #Band0, Band1 for RxA for NCO0
[800,800], #Band0, Band1 for RxB for NCO0
[800,800], #Band0, Band1 for RxC for NCO0
[800,800]] #Band0, Band1 for RxD for NCO0
sysParams.fbNco0 = [800,800] #FBA, FBC for NCO0
sysParams.fbNco1 = [800,800] #FBA, FBC for NCO1
sysParams.fbNco2 = [800,800] #FBA, FBC for NCO2
sysParams.fbNco3 = [800,800] #FBA, FBC for NCO3
Or I should change the calculation somewhere else?
