TM 1-6625-724-13&P0025 000025 00-15Table 1. Error Reported on CADU Error Screen (cont.)Code #Message4106:Filter 1 Ripple Error ACTION: (1) Power the DAU off and on (2) Wait 20 seconds, make ameasurement (3) If error persists, possible hardware failure The 2 kHz, filter 1 has failed the filter ripple test during calibration. Power the DAU off and on,and then try to make a measurement. If the failure persists, send unit to TMDE for repair.Suspect failure of the DAU Acquisition board.4107:Fitter 1 Stop band Gain ACTION: (1) Power the DAU off and on (2) Wait 20 seconds, makea measurement (3) If error persists, possible hardware failureThe 2 kHz, filter 1 has failed the filter stopband test during calibration. Power the DAU off andon, and then try to make a measurement. If the failure persists, send unit to TMDE for repair.Suspect failure of the DAU Acquisition board.4108:Filter 2 Ripple Error ACTION: (1) Power the DAU off and on (2) Wait 20 seconds, make ameasurement (3) If error persists, possible hardware failureThe 2 kHz, filter 2 has failed the filter ripple test during calibration. Power the DAU off and on,and then try to make a measurement. If the failure persists, send unit to TM DE for repair.Suspect failure of the DAU Acquisition board.4109:Filter 2 Stopband Gain ACTION: (1) Power the DAU off and on (2) Wait 20 seconds, make ameasurement (3) If error persists, possible hardware failureThe 2 kHz, filter 2 has failed the filter stopband test during calibration.
