Declaration of Conformity
The Declaration of Conformity (DoC) will contain the following:
•
Product type and model number
•
Marks and countries (e.g. CE, FCC, C-Tick)
•
The appropriate technical statement(s) required by the respective regulatory agencies
•
STEC name and address
•
STEC signature
•
List of all applicable standards to which the drive conforms
Radio Frequency Emissions
The SSD has passed radiated emissions testing (10 meter chamber) with a minimum margin of 4dB
below the EN55022 radiated emissions limits in all applicable customer platforms, without any
required changes to the system platforms.
Emissions testing in a 3 meter chamber for over 1GHz per the FCC limit for Class B was performed
up to 2GHz with the -4dB margin relative to the FCC Class B limit.
In preparation for the new CISPR 22 standard change that may go into effect in the year 2007, the
drives will pass EMI tests up to the higher frequency of either 6GHz or the fifth harmonic of the highest
signal on the drive. This requirement is applicable to all products being qualified after this version is
released.The specification limits are listed in Table 29.
Table 29.
EMI Specification Limits
Radio Frequency Immunity Requirements
This specification is targeted as part of the design for quality and reliability expectations and is not
part of the regulatory requirements. The SSDs meet the following radio frequency immunity
requirements:
•
3 V/m over frequency range of 80 MHz to 1 GHz
•
The signal will be amplitude modulated with a 1KHz sine wave to a depth of 80%
•
Failure criteria: greater than 10% throughput degradation
Class B
1 to 3 GHz is 50dB (uV/m) @ 3 m
Class B
3 to 6 GHz is 54dB (uV/m) @ 3 m
