2.8.2 Conducted noise

Input noise ripple is measured at the host system power supply across an equivalent 80-ohm resistive load on the +12 volt line or an equivalent 15-ohm resistive load on the +5 volt line.

•Using 12-volt power, the drive is expected to operate with a maximum of 120 mV peak-to-peak square-wave injected noise at up to 10MHz.

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

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

Note current.

2.8.3 Voltage tolerance

Voltage tolerance (including noise):

•5V +10% / -7.5%

•12V +10% / -7.5%
