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 24.
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:
EMI Test Site Correlation
STEC will only use EMI test sites that are currently correlated with the customer’s test facilities. STEC
will contact the customer’s engineering staff for the list of approved laboratories.
Verification Samples
STEC will submit the three worst-case drives used to obtain the emissions test data previously
obtained from the customer’s test facilities for verification testing. The Regulator Engineer will use
these drive samples, and others among those submitted for qualification, for emissions verification in
the customer’s systems.
Verification Testing
Verification testing will be performed by the customer’s Compliance Peripheral Group.
