RE: We need another new category, obviously.

Loopback response checks are OK for quick and dirty functional checks, but do not relate to performance of the equipment as it is used, which is either in input mode (ADC) or output mode (DAC), thereby affecting software and hardware.

In addition to interactions which give different performance, there are other problems as well. If they show a level of performance they do not provide a means to partition the performance between the input side and the output side. Worse, in some cases there is the possibility of offsetting errors. (Example might be jitter if common clock is used for ADC and DAC, depending on delays due to buffering.)

Another problem is that to be trustworthy, measurements require trustworthy test equipment and test equipment has to be fit for purpose and kept in a state of good working order and calibration.
