Electromagnetic Immunity

When properly installed in a representative host system, the drive operates without errors or degradation in performance when subjected to the
radio frequency (RF) environment as defined in
Table 8 Radio Frequency Environments

2.10.1 DC Magnetic Field Immunity

Table 9 DC Magnetic Field Immunity
DC Magnetic Field Immunity
1
Field in Gauss at the drive envelope. Testing per procedures 20800109-349 and 20800109-350.
2
Passing Field in Gauss at the drive envelope. In practice, testing is conducted using a fixed distance from the bottom of the mag-
net to the top of the drive. Calibration of the field vs. distance is done with a Hall probe with no magnetic materials present.
3
Testing to be done with magnet.375" dia. x 0.100" Ni-plated NdFeB; B,~11.5 kG, magnetized along its length; the magnet is ori-
ented with the length perpendicular to the drive cover/PCBA. Drive to be properly secured during test.
