2.9.2

Conducted noise

Input noise ripple is measured at the host system power supply across an equivalent 15-ohm resistive load on
the +5V line.

Using 5V power, the drive is expected to operate with a maximum of 100mV peak-to-peak square-wave
injected noise at up to 10 MHz.

Note.

Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write
current.
