Discussion Of Results
This PCI card /rack chassis combination's performance is in the same range as the equipment used to test it. Therefore the results shown may understate its performance, except in the loop-back tests.
The SNR tests may understate the performance of the card due to ambiguities in the performance of the test software (Spectra Lab) when SNR's are this good.
There is some possibility that the instablilty that made it impossible to measure frequency response, only in 24 bit mode, was due to a lack of CPU power on the test computer, which used a K6-300 CPU.
