• It can be attached to a host spinstand, drive tap or AWG.

• Different user has different application.

Magnetic head engineers -> head performance

Media engineers -> media performance

Read channel engineers -> read channel chip performance

Drive engineers -> entire read/write path performance

Need:

• Ethernet connection between PC & Mx board
