Feature
Test Method
Performance
Electrostatic Discharge MIL-STD-883C
Class 1 (>1 kV) - Human Body Model
(ESD) to the Electrical
Pins
Method 3015.4
Electrostatic Discharge Variation of IEC 801-2
(ESD) to the Duplex SC
Receptacle
Products of this type, typically, withstand at least 25 kV
without damage when the Duplex SC Connector
Receptacle is contacted by a Human Body Model probe.
Electromagnetic
Interference (EMI)
FCC Class B
CENELEC EN55022 Class B
(CISPR 22A)
Typically provide a 17 dB margin to the noted standard
limits up to 6 GHz, when tested in a GTEM cell with the
transceiver mounted to a circuit card with a chassis
enclosure.
VCCI Class 1
Immunity
Variation of IEC 801-3
Typically show no measurable effect from a 10 V/m field
swept from 27 MHz to 1 GHz applied to the transceiver
without a chassis enclosure.
