Classification: CPC G | IPC G

Claim 0:
1. A testing apparatus for feedback devices, comprising:
a signal conditioning circuit board that receives a feedback signal;
a central processing unit in communication with the signal conditioning circuit board, the central processing unit configured to:
perform a power check by measuring a voltage and an amperage of the feedback signal, and comparing the measured voltage and the measured amperage to a predefined voltage range and a predefined amperage range, respectively;
check for faulty amplitude by measuring both a high state amplitude and a low state amplitude of the feedback signal, and comparing the high state signal amplitude and the low state signal amplitude to a corresponding predefined amplitude range; and

check for signal symmetry by measuring a duty cycle of the feedback signal, and continually comparing an ON time and an OFF time of the signal to determine if a ratio of the ON time to the OFF time falls within a predefined symmetry threshold.
