gr-genalyzer, a new OOT module to characterize data converter performance
summary
gr-genalyzer is a GNU Radio OOT module that binds to the generalizer C++ library and uses FFTW and IIO device sources to compute IEEE‑standard ADC/DAC metrics. Examples use ADI hardware: ADALM‑PLUTO shows SFDR ~60–61 dBc and CINAD ≈57 dBc; ADRV9002 yields THD ≈ -74 dBFS with SNR ≈80 dB for a 15.36 MS/s LTE profile; AD9081/MXFE produces HD2 ≈ -67 dBFS, HD3 ≈ -70 dBFS and NSD ≈ -140 dBFS/Hz, matching datasheet expectations.
