A-22 DLT4000/DLT4500/DLT4700 Cartridge Tape Subsystem
A.9.2 Conducted Emissions
Limits for Class B equipment are in the frequency range from 0.15 to 30 MHz. The
limit decreases linearly with the logarithm of the frequency in the range from 0.15 to
0.50 MHz.
Table A-22 list the conducted emission limits.

*The limit decreases with the logarithm of the frequency.
A.9.3 Radiated Emissions
Limits of radiated interference field strength, in the frequency range from 30 MHz to
30 GHz at a test distance of 3 and 10 meters, for Class B equipment are:
