Using 5V power, the drive is measured at up to -peak square-wave injected noise at the host system power supply across an equivalent 15-ohm resistive load on the +5V line. B Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write current. 2.9.3 Voltage tolerance Voltage tolerance (including noise): 5V ± 5% 10 Momentus XT Product Manual, Rev.
