Capabilities Description
EMC Requirements
Emissions Emissions are be within the limits specified by the
following requirements.
Enclosure
EN55022 Class B limits for radiated
emissions
AC Mains
EN55022 Class B limits for conducted
emissions
To ensure compliance with the above require-
ments, only high-quality shielded interface
cable should be attached to this instrument.
High-quality cables have a reliable, continuous
outer shield (braid and foil) that has low imped-
ance connections to shielded connector hous-
ings at both ends. The shield of the cable used
to connect to the DSP must be clamped by the
housing where the cable enters the connector.
The cables used for the front panel Digital Out
and the rear panel AES REF OUT must be
wired with the cable shield connected to both
pin 1 and to the shell of the female XLR
connector (sometimes labeled “G” within the
connector). Both of these connections should
be as short as possible, less than 0.25 inch
(0.1 cm).
Immunity, Enclosure, Electrostatic Discharge IEC 801-2 1984

control settings, or temporary loss of function
Immunity, Enclosure, Radio Frequency Electromag-
netic Field
IEC 801-3 1984
No degradation of performance when the instru-
ment is subjected to a 3 V/M electromagnetic field
over the frequency range of 27 MHz to 500 MHz
