Testing was performed in accordance with CISPR 13. 

 

4.1.1 Test 

Methodology 

 
Measurements from 30 MHz to 1000 MHz are taken with broadband antennas. The mast to support the 
antennas is capable of a 1 to 4 meter height range, which meets CISPR and FCC requirements. The antenna 
mast is non-conductive and remotely controllable. 
 
Since radiated emissions, and to a lesser extent, conducted emissions, are a function of cable placement, the 
cable placement is varied to encompass all configurations that an end user would encounter to determine the 
configuration resulting in maximum emissions. At least one cable for each I/O port type is attached to the 
EUT. If peripherals or modules are available, at least one of each available type is installed and noted in the 
report. Generally, only one of each type is used unless good engineering judgment dictates that the use of 
more will affect emission levels. Excess cable lengths are arranged into a 30 x 40cm bundle. Cables requiring 
non-standard lead dress are recorded in the report. 
 
4.1.2 

Site and Test Description 

 
The test facility is a specially designed and constructed open area test site. Two test sites are used (Distances: 
3 meters and 10 meters) for CISPR and FCC testing. 
 
All test sites include a metal ground plane constructed of 22-gauge sheet metal. Each site contains a 2.5 meter 
diameter turntable for floor standing equipment, and a wooden table measuring 1.5 x 1.5 x 0.8 meters for 
table top equipment to facilitate testing, also it has heat and air conditioning systems to control environmental 
test conditions. 
 
Radiated emission measurements were performed according to the procedures in ANSI C63.4 (2003). All 
measurements were performed in Open Area Test Sites.
