Electromagnetic Field Specifications
Electromagnetic Emissions
Once the internal tape drive is mounted into an enclosure and grounded, the internal drive complies with FCC Class A; the external tape drive complies with the FCC Class B
limits.
Conducted Emissions
Limits for Class B equipment are in the frequency range from 0.15 to 30 MHz.
Table 1. Conducted Emissions
Frequency Range
0.15 to 0.50 MHz
0.50 to 5 MHz
5 to 30 MHz
* The limit decreases linearly with the logarithm of the frequency.
Radiated Emissions
Limits of radiated interference field strength, in the frequency range from 30 MHz to 1000 MHz at a test distance of 10 meters, are listed in Table 2.
