The measurement setup was made according to EN 55013:2001+A1+A2 in a shielded room.
The measurement equipment like test receivers, quasi-peak detector and artificial mains
network (AMN) are in compliance with CISPR 16-1 series standards.
network (AMN) are in compliance with CISPR 16-1 series standards.
The tested object was set-up on a wooden table. The EUT was set 0.8m away from the
AMN. The cord longer than necessary to be connected to the AMN was folded forth and
back parallel so as to form a bundle with a length between 0.3m and 0.4m.

The disturbance voltage was determined according to clause 5.3 of EN 55013:2001+A1+A2
while measuring the line and neutral conductor by turns.

The following figures and tables were those measured by an automatic measuring system.
Both quasi-peak and average measurements were performed. In the following spectral
diagram, “x” means quasi-peak test results and “+” means average test results.

The disturbance power was determined according to clause 5.6 of EN 55013:2001+A1+A2.
The disturbance power was measured at the following leads/ports:
The disturbance power was measured at the following leads/ports:
AC mains port, DC power port, Audio input port, Video output port and USB port.
The maximum disturbance power at each frequency was found by moving the absorption
clamp along the power or the signal lead. When testing video output leads, 75
