DFT Limit Too Big While performing 2.0cc compliance calibration, the signal
processor ensures that the measured compliance at a nominal
gain setting allows for enough span in DFT calculation.
Subcodes: Out-of-range nominal DFT base.
Likely Causes: Clogged probe; mic circuit; filter circuit;
wrong cavity size used; bad probe SPL calibration data.
Invalid Speaker Level Input to Mux Signal processor checks to ensure that when the probe
speaker level is to be written to EEPROM during pseudo-
code execution, that the probe speaker mux is set to the
corresponding position.
Subcodes: Invalid position.
Likely Causes: Software error.
Probe VCA DAC Level Out of Range Signal processor checks to ensure that when the probe
speaker level is to be written to EEPROM when commanded
by the Control Processor (during Probe SPL calibration), that
the value is within a the valid range of 0 to 255 DAC counts.
Subcodes: The invalid level.
Likely Causes: Clogged probe tube; probe tone oscillator;
probe tone VCA.
