4.2 MAXIMUM E.I.R.P. SPECTRAL DENSITY 
4.2.1  LIMITS 
EN300 328 clause 4.3.2 
For wide band modulations other then FHSS (e.g. DSSS, OFDM, etc.), the maximum e.i.r.p. 
spectral density is limited to 10 mW per MHz. 
4.2.2  TEST METHOD 
EUT operation status: 
Keep EUT on transmitting mode by the software provided by 
manufacturer. 
Pretest the EUT at different transmission rate and report show 
the worst case data. 
     
Test channel: 
802.11b/g 
Lowest channel: (2412MHz),Middle channel: (2442MHz), 
Highest channel: (2472MHz) 
Test condition: 
Normal test conditions. 
Test equipment used: 
Refer to section 3.4 
Test procedure: 
1.  Connect a low attenuation cable from the antenna port to the 
spectrum. 
1.  Set spectrum analyzer center frequency is centered of test 
channel; Set RBW and VBW = 1MHz. Sweep = auto. Span 
is wide enough to cover the complete power envelope of the 
signal of the EUT. Detector function = Peak. Trace = Max 
hold; find the peak value of the power envelope. Save the 
trace. 
2.  Set the Centre Frequency is equal to the frequency find in 
step 2; RBW and VBW=1MHz, Span=3M, Sweep time=1 
min, Detector function= Average, Trace= Max hold. 
3.  Find the peak value of the power envelope and record the 
frequency. Save the trace. 
Remark:    
Pre-scan all the rate, found that:  
11Mbps of rate is the worst case of 802.11b;  
54Mbps of rate is the worst case of 802.11g ;
