Check the DAS supply voltage (AJ-CONTROL / AJ-CONVERTER PWBs)
Verify the DC supply voltages the DAS power supply unit delivers to the AJ-CONVERTER and AJ-CONTROL PWBs through connectors PCN2 and PCN3, and check the ripple on those same voltages with an oscilloscope. This is a bench check with the power cable and I/O cable already connected — you are reading supply rails at the board connectors, not commanding a scan.
Applies to
Activion16 (TSX-031A), CDAS-035A/2A data acquisition section (AJ-CONTROL / AJ-CONVERTER PWBs). No model- or revision-specific restriction beyond that generation is stated in source for this task; the CDAS-035A/1A generation has its own byte-identical-values procedure at §2.8.7 (Related), with Control-16/Converter-16 board names in place of AJ-CONTROL/AJ-CONVERTER.
