Site and Test Description 

 
Testing was performed in accordance with CISPR 13 
 
The unit was placed on 5.8 m by 6.4m reference ground plane and a power cord was extended to 6 m in 
length and laid in a straight line across a 0.8m high non-conducting support.  An absorbing clamp was 
placed around the power cord and was moved along the lead to determine the maximum value of 
disturbance power. This test was performed on all other leads of length 25 cm or more, measured by 
means of the absorbing clamp. 
 
Initially a scan was made in peak mode from 30 MHz to 300 MHz.  Selected frequencies were identified 
and signals were measured with quasi peak (QP) and average (AV) detectors.  The results were compared 
with the appropriate limits.
