General Description and Specifications

Quantum DLT 7000 Tape System 1-13

1.3.15 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

listed in the following table.

Table 1-16 Radiated Emissions

Frequency Range Quasi-peak limits dB (µV/m)

Quasi-peak Average

30 to 230 MHz 30 40

230 to 1000 MHz 37 46

Above 1000 MHz N/A 54

* The limit decreases with the logarithm of the frequency.

1.3.16 Susceptibility

The following table lists radiated, magnetic radiated, and conducted

susceptibility for the tape drive.

Table 1-17 Radiated, Magnetic Radiated, and Conducted Susceptibility

Radiated - High Frequency, Electric Fields, 1 to 1000 MHz

3 V/m (rms) 80% modulated 1 kHz No errors, no screen distortion

S/W recoverable errors No

hardware failure

Magnetic Radiated - Low Frequency, Magnetic Fields, 10 to 3000 kHz

100 dB (pt) @ 10 kHz declining to 80 dB (pt) @

from the power source. The maximum energy in a single pulse from the transient

generator must be limited to 2.5 W)
