Abstract
Automated power noise susceptibility test systems are provided for one or more storage devices. A system includes a host; storage devices; and multiple noise injection modules. Each noise injection module includes: a first relay to a third relay, which are coupled to a first path or a second path. The first path includes: an operational amplifier for generating a high noise function; a first variable regulator for generating a first or second regulated power supply voltage; and a capacitor injection circuit for generating low noise function and a first power noise. The second path includes: a second variable regulator for generating a third or fourth regulated power supply voltage and a power amplifier injection circuit for generating a second power noise. The third relay selectively provides the storage device the first power noise or the second power noise.
