Quantum Instruments DLT 7000 manual Radiated Emissions, Susceptibility

General Description and Specifications

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.

1.3.16Susceptibility

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) @	No errors, no screen distortion
1 Mhz

Conducted (The transient voltage is the actual peak voltage above the normal ac voltage from the power source. The maximum energy in a single pulse from the transient generator must be limited to 2.5 W)

Fast Transient (Bursts) for	2 kV	S/W recoverable errors	No
Power and Data Cables		hardware failures
High Energy Transient	1.2 kV	No errors
Voltage for Power Cables	2.5 kV	S/W recoverable errors	No
		hardware failure
Low-Level Conducted	3 V (rms) 80%	No errors	S/W
Interference	modulated 1 kHz	recoverable errors	No
		hardware failure
