Abstract

Noise injection systems and methods for conducting power noise susceptibility tests on memory systems, including solid state drives. A noise injection system comprises a power selector to deliver a voltage at a first or second level according to a frequency level indicated by a frequency select signal; a noise signal relay to receive a frequency noise signal and to deliver a low or high frequency noise component of the frequency noise signal according to the frequency level of the frequency select signal; and an amplification assembly, responsive to the frequency select signal and which receives the first or second level voltage based on the frequency level of the frequency select signal, receives and amplifies the high frequency noise component when the frequency select signal indicates a high frequency level, and receives and amplifies the low frequency noise component when the frequency select signal indicates a low frequency level.
