    Troubleshooting Comparator Programming Test The purpose of this test is to verify the programming path to each of the comparators. Comparator/DAC Test This test is executed only if all probes are detached. This test uses the pod, bonus, and calibration DACs, the calibration oscillator (implemented in the interface FPGA), the comparators, the connections between the comparators and the Analysis chip, and the activity indicators in the Analysis chip.
