| Equipment Used: | Test media was a custom CD created with CoolEdit Pro 1.1 in 32 bit mode, converted to 16 bit with 0.53 bits of spectrally uniform, Gaussian distributed dither; and burned onto Ricoh media using a Plexstor R412C and EZ CD Deluxe 3.5. Signals processed into computer using an LynxONE. Signal analysis with SpectraLab 3.32.14. | |||

Discussion Of Results
The relatively high jitter and high Frequency IM distortion suggest problems handling program material at high frequencies. The relatively poor SNR with a signal present suggests that the DAC has modulation noise. This in turn, suggests that the DAC is nonlinear or missing bits.
