I'm trying to evaluate a customer board with RF analyzer (2020.2)
The board has XCZU48DR2FFVG1517 so RF_Analyzer_48DR_32mA.bit file from RF Analyzer installation directory was loaded.
There is one thing I like to get answer, which could not find anything from UG1309.
1. The DAC0 is set to 8Gsps, I/Q to real, IMR low pass, interpolate x2, NCO = 1200MHz, QMC disabled, Zone 1, current = 31.981mA and CF = 200MHz for example.
2. ADC01 is set to 4Gsps, I/Q output, Cal Mode 2, decimation /2, NCO = 1200MHz, QMC disabled and Zone 1
On the ADC FFT page, the signal is at ~ -25dBFS with DAC current at 31.981mA. Was it right level?
It became ~ -30dBFS when changing DAC current to 20mA.
Any ideas? Thanks.
